Use WCF Test Client to test WCF Service Application

Add Service Reference in Visual Studio

With the service running, right click the project that will contain the WCF client proxy and select

Add

>

Service Reference

. In the

Add Service Reference Dialog

, type in the URL to the service you want to call and click the

Go

button. The dialog will display a list of services available at the address you specify. Double click the service to see the contracts and operations available, specify a namespace for the generated code, and click the

OK

button.

Location of Files Generated by the Test Client

By default, WCF Test Client stores generated client code and configuration files in the “%appdata%\Local\temp\Test Client Projects” folder. This folder is deleted after WCF Test Client exits. If a configuration file is modified in WCF Test Client and the Always Regenerate Config When Launching Services option is disabled, the modified file is copied to the “CachedConfig” folder under “My Documents\Test Client Projects” with a mapping (metadata-address-to-file-name) XML file as an index.

You can also start WCF Test Client in a command line, use the

/ProjectPath

switch to specify a new desired path for storing generated files, or use the

/RestoreProjectPath

switch to restore the default location. The syntax is as follows:


wcfTestClient.exe /ProjectPath [desired location]

Running this command does not open WCF Test Client. Only the folder location is changed. You can run this command whether WCF Test Client is running or not. The new location is applied when WCF Test Client is restarted. The location information can be saved in registry, or in the WcfTestClient.exe.option file in the “%appdata%\Local\temp\Test Client Projects” folder.

Testing a WCF Service

After completing the coding, I would like to inquire about the setup and operation of a wcf service .

After developing my service, I can effortlessly launch it in the browser by simply right-clicking it in VS and selecting the “Run” option.

To verify the functionality of the service, I plan to generate a new C# project and include a service reference to my service (

.svc

).

The service reference cannot be found when attempting to add it, such as with

http://localhost:55129/Cars.svc

.

Is it necessary to have the service project operational to incorporate it?

Do I have to configure it on IIS? Or do users typically execute the WCF project directly within Visual Studio?

This is the error message I receive while attempting to include the service endpoint.

An error occurred while downloading


http://localhost:55129/Cars.svc/_vti_bin/ListData.svc/$metadata

. The HTTP status 400: Bad Request of request failed resulted in the following error message:

http://localhost:55129/Cars.svc

. The service

http://localhost:55129/Events.svc

did not support application/soap+ xml; charset=utf -8. the client and service bindings may be mismatched . The remote server returned an error message stating that it cannot process the content type ‘application/soap+xml; charset=utf-8’ because it was not the expected type ‘text/xml; charset=utf-8’. If the service is defined in the current solution, try building the solution and adding the service reference again.

Solution:

To generate client proxies, the development web service must be operational.

IIS hosting is highly convenient because it keeps running continuously, even if you have closed your solution.

Using the WCF Client

To use the WCF client, create an instance of the WCF client, and then call its methods, as shown in the following code.

// Create a client object with the given client endpoint configuration.
CalculatorClient calcClient = new CalculatorClient("CalculatorEndpoint");
// Call the Add service operation.
double value1 = 100.00D;
double value2 = 15.99D;
double result = calcClient.Add(value1, value2);
Console.WriteLine("Add({0},{1}) = {2}", value1, value2, result);
' Create a client object with the given client endpoint configuration.
Dim calcClient As CalculatorClient = _
New CalculatorClient("CalculatorEndpoint")

' Call the Add service operation.
Dim value1 As Double = 100.00D
Dim value2 As Double = 15.99D
Dim result As Double = calcClient.Add(value1, value2)
Console.WriteLine("Add({0},{1}) = {2}", value1, value2, result)

WCF Test Client User Interface

You can use WCF Test Client with a single service or multiple services.

Service Operations

The left pane of the WCF Test Client main window lists all the available services, along with their respective endpoints and operations.

When you double-click an operation, you can view its content in the right pane inside a new tab with the operation’s name.

The left pane also lists client configuration files. Double-click any of the items to display the content of the file in a new tabbed window in the right pane.

Entering Test Parameters

To view the test parameters, double-click an operation to open it in the right pane. The parameters are showed in Formatted view by default, and you can enter arbitrary values for the parameters to test the service.

To view the message’s XML, click XML. To send them to the service, click Invoke.

For a DataSet parameter, click the … button next to Edit… to edit it in a new window showing the DataGrid. Notice the appearance of the Copy DataSet and Paste DataSet buttons. If the schema of the DataSet object is unknown upon the first edit, the DataGrid is empty. You have to paste a DataSet object with the same schema into the current object in the DataGrid. (Notice that you need to copy the schema from somewhere else before the paste operation.) You can also copy a Dataset object for future usage by clicking the Copy DataSet button.

The service’s response appears below the test parameters.

Note

If the expected return value is a string, the result will be displayed as a quoted string even though the input provided was not in quotes.

If you specified a particular operation as one-way when you created the contract for the service, no service response is displayed. As soon as the message is queued for delivery, a dialog box pops up to notify you that the message was successfully sent.

Session Support

The Start a new proxy check box in a service operation’s tab enables you to toggle session support. This box is cleared by default.

When you enter test parameters for a specific operation (or another operation in the same service endpoint) and click Invoke multiple times with the check box cleared, these operations share one proxy and the service status is persisted across multiple operations.

If the Start a new proxy check box is checked, a new proxy is started for each Invoke, the previous session scenario is ended, and the service status is reset.

Editing Client Configuration

The left pane of the WCF Test Client main window lists client configuration files. Double-click any of the items to display the contents of the file in the right pane.

Edit with Service Configuration Editor

Right-click Config File in the left pane and select the context menu Edit with SvcConfigEditor. Service Configuration Editor is launched with the client configuration content. You can edit the configuration and save it within the tool.

After saving the file in Service Configuration Editor, WCF Test Client displays a warning message to inform you that the file has been modified outside and asks whether you would like to reload it.

If you select Yes, the configuration content in the “Client.dll.config” tab reflects the changes you made in the editor.

If you select No, the configuration content in the “Client.dll.config” tab remains unchanged and the modified content is automatically saved to the source file.

Restore to Default Configuration

If you want to cancel all the changes and restore to the default client configuration, right-click Config File in the left pane and select the context menu Restore to Default Config. The default configuration value is loaded and content in “Client.dll.config” tab is restored.

Validate Changes

When saved changes are being loaded in WCF Test Client, the configuration is checked for validity against WCF schema. If errors are found, a dialog box is displayed to show error details.

During proxy generation, binary compiling, or service invoking, menu items that support editing (that is, “Edit …”, “Restore …”, and so on) are disabled. Service invocation is also disabled when loading updated configuration to WCF Test Client.

Persist Client Configuration

The Tools->Options->Client Configuration tab contains an Always Regenerate Config When Launching Services option, which is enabled by default. This option specifies that every time WCF Test Client loads a service, it regenerates a configuration file based on the latest service contract and service App.config files.

If you have edited the client configuration for your WCF service and want to always use this updated file to debug your service, you can uncheck the Regenerate option. By doing so, even when you update the service and reopen WCF Test Client, the Client.dll.config file is the one you updated previously instead of a regenerated one based on the updated service.

However, you might need to edit the configuration file to make it consistent with the regenerated proxy. If the regenerated proxy and configuration file are mismatched due to an updated service, errors will occur when the service is invoked.

Caution

If you have modified the client configuration file and select to reuse it in the future, you can find the file in the following location:

\Documents and Settings\[User Account]\My Documents\Test Client Projects.

Any updated credential information stored to the client configuration file is protected by the Access Control List (ACL) of this folder.

Adding, Removing and Refreshing Services

Add Service

Click File->Add Service to add a service to WCF Test Client. You are then required to type the URI (endpoint address) of the service to be added. The service’s address can be a mex address or WSDL address.

You can also find a list of 10 recently added services’ endpoints in the Recent Services submenu. If you select one of them, the specified service is added to WCF Test Client.

You can also right-click the root of service tree My Service Projects, and select Add Service to achieve the same result.

During proxy generation, binary compiling, or service invocation, menu items that support adding a service are disabled. Service invocation is also disabled.

Remove Service

Right-click the service root of the service to be removed, and select Remove Service to remove a service from WCF Test Client.

During proxy generation, binary compiling, or service invocation, menu items that support removing a service are disabled. Service invocation is also disabled.

Refresh Service

If a change is made to the service while WCF Test Client is running and you want to ensure that the WCF Test Client implementation for that service is up-to-date, right-click the service root of the service, and select Refresh Service. Note that after refreshing, the service status is reset.

During proxy generation, binary compiling, or service invocation, menu items that support refreshing a service are disabled. Service invocation is also disabled.

Scenarios for Using Test Client

The following sections discuss the most common scenarios in which you can use WCF Test Client to streamline your development process.

Inside Visual Studio

WCF Service Host Starts WCF Test Client with a Single Service

After you create a new WCF service project and press F5 to start the debugger, the WCF Service Host begins to host the service in your project. Then, WCF Test Client opens and displays a list of service endpoints defined in the configuration file. You can test the parameters and invoke the service, and repeat this process to continuously test and validate your service.

WCF Service Host Starts WCF Test Client with Multiple Services

You can also use WCF Test Client to help debug a service project that contains multiple services. When WCF Test Client opens, it automatically iterates the list of services in your project and opens them for testing.

Outside Visual Studio

You can also invoke the WCF Test Client (WcfTestClient.exe) outside Visual Studio to test an arbitrary service on the Internet. To locate the tool, go to the following location:


C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\Common7\IDE

(where community can be one of “Enterprise”, “Professional” or “Community” depending on which level of Visual Studio is installed on the machine)

To use the tool, double-click the file name to open it from this location, or launch it from a command line.

WCF Test Client takes an arbitrary number of URIs as command line arguments. These are the URIs of services that can be tested.


wcfTestClient.exe URI1 URI2 …

After the WCF Test Client window is opened, click File->Add Service, and enter the endpoint address of the service you want to open.

In this article

After you create a service, the next step is to create a WCF client proxy. A client application uses the WCF client proxy to communicate with the service. Client applications usually import a service’s metadata to generate WCF client code that can be used to invoke the service.

The basic steps for creating a WCF client include the following:

  1. Compile the service code.

  2. Generate the WCF client proxy.

  3. Instantiate the WCF client proxy.

The WCF client proxy can be generated manually by using the Service Model Metadata Utility Tool (SvcUtil.exe) for more information see,

ServiceModel Metadata Utility Tool (Svcutil.exe)

. The WCF client proxy can also be generated within Visual Studio using the

Add Service Reference

feature. To generate the WCF client proxy using either method the service must be running. If the service is self-hosted you must run the host. If the service is hosted in IIS/WAS you do not need to do anything else.

Example

The following code example shows a service contract created for a service.

// Define a service contract.
[ServiceContract(Namespace="http://Microsoft.ServiceModel.Samples")]
public interface ICalculator
{
    [OperationContract]
    double Add(double n1, double n2);
    // Other methods are not shown here.
}
' Define a service contract.
 _
Public Interface ICalculator
      _
    Function Add(ByVal n1 As Double, ByVal n2 As Double) As Double
    ' Other methods are not shown here.
End Interface

The ServiceModel Metadata utility tool and

Add Service Reference

in Visual Studio generates the following WCF client class. The class inherits from the generic

ClientBase

class and implements the

ICalculator

interface. The tool also generates the

ICalculator

interface (not shown here).

public partial class CalculatorClient : System.ServiceModel.ClientBase, ICalculator
{
    public CalculatorClient()
    {}

    public CalculatorClient(string endpointConfigurationName) :
            base(endpointConfigurationName)
    {}

    public CalculatorClient(string endpointConfigurationName, string remoteAddress) :
            base(endpointConfigurationName, remoteAddress)
    {}

    public CalculatorClient(string endpointConfigurationName,
        System.ServiceModel.EndpointAddress remoteAddress) :
            base(endpointConfigurationName, remoteAddress)
    {}

    public CalculatorClient(System.ServiceModel.Channels.Binding binding,
        System.ServiceModel.EndpointAddress remoteAddress) :
            base(binding, remoteAddress)
    {}

    public double Add(double n1, double n2)
    {
        return base.Channel.Add(n1, n2);
    }
}
Partial Public Class CalculatorClient
    Inherits System.ServiceModel.ClientBase(Of ICalculator)
    Implements ICalculator

    Public Sub New()
        MyBase.New
    End Sub

    Public Sub New(ByVal endpointConfigurationName As String)
        MyBase.New(endpointConfigurationName)
    End Sub

    Public Sub New(ByVal endpointConfigurationName As String, ByVal remoteAddress As String)
        MyBase.New(endpointConfigurationName, remoteAddress)
    End Sub

    Public Sub New(ByVal endpointConfigurationName As String,
        ByVal remoteAddress As System.ServiceModel.EndpointAddress)
        MyBase.New(endpointConfigurationName, remoteAddress)
    End Sub

    Public Sub New(ByVal binding As System.ServiceModel.Channels.Binding,
        ByVal remoteAddress As System.ServiceModel.EndpointAddress)
        MyBase.New(binding, remoteAddress)
    End Sub

    Public Function Add(ByVal n1 As Double, ByVal n2 As Double) As Double
        Implements ICalculator.Add
        Return MyBase.Channel.Add(n1, n2)
    End Function
End Class

Debugging Exceptions Thrown by a Client

Many exceptions thrown by a WCF client are caused by an exception on the service. Some examples of this are:

When these types of exceptions occur, the best way to solve the problem is to turn on tracing on the service side and determine what exception occurred there. For more information about tracing, see

Tracing

Closing WCF Test Client

You can close WCF Test Client in the following ways:

  • On the File menu, click Exit. Alternatively, in the WCF Test Client main window, click Close. Both of these actions also shut down WCF Service Auto Host and stop the Visual Studio debugging process if WCF Test Client was launched by Visual Studio.

  • Right-click the WCF Service Host icon in the notification area, and then click Exit. This shuts down both WCF Service Auto Host and WCF Test Client and stops the Visual Studio debugging process.

Tests wcf service in the browser

Despite having

in the configuration file, I am still unable to execute a simple WCF web method through the browser.

The code source is extremely simple.

For the interface:


[ServiceContract] public interface IService1 { [OperationContract] [WebInvoke(Method = "GET", ResponseFormat = WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.Bare)] string GetData(); [OperationContract] CompositeType GetDataUsingDataContract(CompositeType composite); // TODO: ajoutez vos opérations de service ici }

And for the implementation:


public string GetData() { return ("{'code':'yes'}"); }

The
visual studio wcf
service tester which is already integrated, effectively utilizes this technique and yields the result of

{'code':'yes'}

.

When attempting to access

http://localhost:54421/Service1.svc/GetData

in the browser, the page appears to be blank. What steps can I take to fix this issue?

Solution 1:

I am implementing varied endpoint behavior for REST calls to accommodate diverse clients. Please refer to the following configuration for more information.

Include an endpoint in your service definition that utilizes this behavior.

Your service can now be accessed from both the browser and WCF client. If you wish to access it via the browser, use the following method:


http://localhost:54421/Service1.svc/easy/GetData

The purpose of ServiceMetadata is explained in the documentation, which can be accessed through the provided link. In essence, ServiceMetadata allows your service to provide information about itself, enabling external developers to create proxy clients.

Solution 2:

Typically, when attempting to view json results in a browser, they are not displayed. Instead, you may either encounter a blank page (in which case you can view the source) or be asked to download the file.

Add-ons are available for Firefox that allow you to view JSON and test web services with the Poster add-on.

You may want to consider using Pretty JSON if you are utilizing Google Chrome.

How to test a client of a WCF service

I possess a
WCF service
that has one method,

GetNextObjectInList(int id)

, which interacts with a database.

The functioning of the WCF service is somewhat similar to this.


public class MyService : IDisposable { public MyService() { this.IntializeDBConnection(); } public int GetNextObjectInList(int id) { /* uses DB connection */ } /* Dispose releases DB connection */ }

As a result, the complexity of client code is kept to a minimum.


public void UseNextElementInList() { IMyService svc = new MyServiceClient(); int nextID = svc.GetNextObjectInList(this.ID); /* use object */ }

I have created unit tests to conduct tests on the WCF services objects. However, I am interested in testing the consumer code for different aspects such as timing, performance, and error handling. Unfortunately, I am unsure of how to design my tests in a way that prevents the Service from accessing the database. “””.

The majority of my tests, such as those that are performed on the service’s objects, involve the creation of an in-memory DB. However, I am unsure of how to establish a connection between the service and the in-memory DB without implementing test-specific code within the service.

Solution:

To facilitate unit testing, I recommend setting up a test service. In such cases, I usually create a test project configuration that mirrors the real one, except that the address is set to local host and the type is changed to my test service class.

If you are working with a VS Test Project, you have the option to utilize the classinitialize / ClassCleanup attributes for both setting up and tearing down the service.


[ClassInitialize()] public static void MyClassInitialize(TestContext testContext) { mHost = new ServiceHost(typeof(TestService)); mHost.Open(); return; } [ClassCleanup()] public static void MyClassCleanup() { if(mHost != null) { mHost.Close(); } return; }

Within the TestService class, which implements IMyService, you have the freedom to define any required behavior for testing the client, without concerns about your unit tests disrupting your production code.

Location of Files Generated by the Test Client

By default, WCF Test Client stores generated client code and configuration files in the “%appdata%\Local\temp\Test Client Projects” folder. This folder is deleted after WCF Test Client exits. If a configuration file is modified in WCF Test Client and the Always Regenerate Config When Launching Services option is disabled, the modified file is copied to the “CachedConfig” folder under “My Documents\Test Client Projects” with a mapping (metadata-address-to-file-name) XML file as an index.

You can also start WCF Test Client in a command line, use the

/ProjectPath

switch to specify a new desired path for storing generated files, or use the

/RestoreProjectPath

switch to restore the default location. The syntax is as follows:


wcfTestClient.exe /ProjectPath [desired location]

Running this command does not open WCF Test Client. Only the folder location is changed. You can run this command whether WCF Test Client is running or not. The new location is applied when WCF Test Client is restarted. The location information can be saved in registry, or in the WcfTestClient.exe.option file in the “%appdata%\Local\temp\Test Client Projects” folder.

WCF Test Client User Interface

You can use WCF Test Client with a single service or multiple services.

Service Operations

The left pane of the WCF Test Client main window lists all the available services, along with their respective endpoints and operations.

When you double-click an operation, you can view its content in the right pane inside a new tab with the operation’s name.

The left pane also lists client configuration files. Double-click any of the items to display the content of the file in a new tabbed window in the right pane.

Entering Test Parameters

To view the test parameters, double-click an operation to open it in the right pane. The parameters are showed in Formatted view by default, and you can enter arbitrary values for the parameters to test the service.

To view the message’s XML, click XML. To send them to the service, click Invoke.

For a DataSet parameter, click the … button next to Edit… to edit it in a new window showing the DataGrid. Notice the appearance of the Copy DataSet and Paste DataSet buttons. If the schema of the DataSet object is unknown upon the first edit, the DataGrid is empty. You have to paste a DataSet object with the same schema into the current object in the DataGrid. (Notice that you need to copy the schema from somewhere else before the paste operation.) You can also copy a Dataset object for future usage by clicking the Copy DataSet button.

The service’s response appears below the test parameters.

Note

If the expected return value is a string, the result will be displayed as a quoted string even though the input provided was not in quotes.

If you specified a particular operation as one-way when you created the contract for the service, no service response is displayed. As soon as the message is queued for delivery, a dialog box pops up to notify you that the message was successfully sent.

Session Support

The Start a new proxy check box in a service operation’s tab enables you to toggle session support. This box is cleared by default.

When you enter test parameters for a specific operation (or another operation in the same service endpoint) and click Invoke multiple times with the check box cleared, these operations share one proxy and the service status is persisted across multiple operations.

If the Start a new proxy check box is checked, a new proxy is started for each Invoke, the previous session scenario is ended, and the service status is reset.

Editing Client Configuration

The left pane of the WCF Test Client main window lists client configuration files. Double-click any of the items to display the contents of the file in the right pane.

Edit with Service Configuration Editor

Right-click Config File in the left pane and select the context menu Edit with SvcConfigEditor. Service Configuration Editor is launched with the client configuration content. You can edit the configuration and save it within the tool.

After saving the file in Service Configuration Editor, WCF Test Client displays a warning message to inform you that the file has been modified outside and asks whether you would like to reload it.

If you select Yes, the configuration content in the “Client.dll.config” tab reflects the changes you made in the editor.

If you select No, the configuration content in the “Client.dll.config” tab remains unchanged and the modified content is automatically saved to the source file.

Restore to Default Configuration

If you want to cancel all the changes and restore to the default client configuration, right-click Config File in the left pane and select the context menu Restore to Default Config. The default configuration value is loaded and content in “Client.dll.config” tab is restored.

Validate Changes

When saved changes are being loaded in WCF Test Client, the configuration is checked for validity against WCF schema. If errors are found, a dialog box is displayed to show error details.

During proxy generation, binary compiling, or service invoking, menu items that support editing (that is, “Edit …”, “Restore …”, and so on) are disabled. Service invocation is also disabled when loading updated configuration to WCF Test Client.

Persist Client Configuration

The Tools->Options->Client Configuration tab contains an Always Regenerate Config When Launching Services option, which is enabled by default. This option specifies that every time WCF Test Client loads a service, it regenerates a configuration file based on the latest service contract and service App.config files.

If you have edited the client configuration for your WCF service and want to always use this updated file to debug your service, you can uncheck the Regenerate option. By doing so, even when you update the service and reopen WCF Test Client, the Client.dll.config file is the one you updated previously instead of a regenerated one based on the updated service.

However, you might need to edit the configuration file to make it consistent with the regenerated proxy. If the regenerated proxy and configuration file are mismatched due to an updated service, errors will occur when the service is invoked.

Caution

If you have modified the client configuration file and select to reuse it in the future, you can find the file in the following location:

\Documents and Settings\[User Account]\My Documents\Test Client Projects.

Any updated credential information stored to the client configuration file is protected by the Access Control List (ACL) of this folder.

Adding, Removing and Refreshing Services

Add Service

Click File->Add Service to add a service to WCF Test Client. You are then required to type the URI (endpoint address) of the service to be added. The service’s address can be a mex address or WSDL address.

You can also find a list of 10 recently added services’ endpoints in the Recent Services submenu. If you select one of them, the specified service is added to WCF Test Client.

You can also right-click the root of service tree My Service Projects, and select Add Service to achieve the same result.

During proxy generation, binary compiling, or service invocation, menu items that support adding a service are disabled. Service invocation is also disabled.

Remove Service

Right-click the service root of the service to be removed, and select Remove Service to remove a service from WCF Test Client.

During proxy generation, binary compiling, or service invocation, menu items that support removing a service are disabled. Service invocation is also disabled.

Refresh Service

If a change is made to the service while WCF Test Client is running and you want to ensure that the WCF Test Client implementation for that service is up-to-date, right-click the service root of the service, and select Refresh Service. Note that after refreshing, the service status is reset.

During proxy generation, binary compiling, or service invocation, menu items that support refreshing a service are disabled. Service invocation is also disabled.

REST WCF Service for Web Applications in ASP.NET Hands-On
REST WCF Service for Web Applications in ASP.NET Hands-On

Test the Service

Visual Studio provides a built-in WCF Service Host application and a WCF Test Client application that enable you to test your
service without having to create a client application.

  1. SqlBookWCF should already be set as your startup project as evidenced by its bold appearance in the
    Solution Explorer; however, if it does not appear in bold, right-click the
    SqlBookWCF project; then and select
    Set as StartUp Project from the context menu.
  2. From the main menu, click
    DEBUG > Start Without Debugging.

    This starts the service and invokes the WCF Test Client window. The left pane shows the endpoint for your service and the
    operations that are exposed.

  3. In the left pane, double-click the

Scenarios for Using Test Client

The following sections discuss the most common scenarios in which you can use WCF Test Client to streamline your development process.

Inside Visual Studio

WCF Service Host Starts WCF Test Client with a Single Service

After you create a new WCF service project and press F5 to start the debugger, the WCF Service Host begins to host the service in your project. Then, WCF Test Client opens and displays a list of service endpoints defined in the configuration file. You can test the parameters and invoke the service, and repeat this process to continuously test and validate your service.

WCF Service Host Starts WCF Test Client with Multiple Services

You can also use WCF Test Client to help debug a service project that contains multiple services. When WCF Test Client opens, it automatically iterates the list of services in your project and opens them for testing.

Outside Visual Studio

You can also invoke the WCF Test Client (WcfTestClient.exe) outside Visual Studio to test an arbitrary service on the Internet. To locate the tool, go to the following location:


C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\Common7\IDE

(where community can be one of “Enterprise”, “Professional” or “Community” depending on which level of Visual Studio is installed on the machine)

To use the tool, double-click the file name to open it from this location, or launch it from a command line.

WCF Test Client takes an arbitrary number of URIs as command line arguments. These are the URIs of services that can be tested.


wcfTestClient.exe URI1 URI2 …

After the WCF Test Client window is opened, click File->Add Service, and enter the endpoint address of the service you want to open.

Yes, you can call those methods in a browser, if your service is configured properly, though you have the URL syntax wrong.

To call WCF methods from a browser, you need to do two things:

  • Use

    [WebGet]

    and

    [WebInvoke]

    attributes on your methods, which you have done.
  • Use a

    webHttpBinding

    for the endpoint of your service and enable the

    webHttp

    behavior. See http://weblogs.asp.net/kiyoshi/archive/2008/10/08/wcf-using-webhttpbinding-for-rest-services.aspx for a sample configuration, but the relevant parts are:

Once that is done, WCF will start listening for URL request and route them to your appropriate web methods. You can set up URL templates in your

WebGet

or

WebPost

attributes that map URL segments to method parameters, if you want to make your URLs “cleaner”, but that’s optional. Otherwise, you pass parameters the same way you pass parameter to any other URL, using the parameter delimiter:


http://localhost:49815/MyService.svc/methodName?parameterName=value

Note that the default for a web-invoked method is a POST. Technically you can do these through a browser but it’s much harder (you’d have to make a local HTML form, or use your Javascript console, or something similar), but the

WebGet

methods can be invoked just by requesting the correct URL.

Also, if your methods return anything more complex than a string, WCF will try to serialize it as JSON; you may need to ‘view source’ on the resulting page to see it.

As you are working with REST based service, change your web.config like below-

We have finished modifying the existing

NorthwindService

to be a RESTful WCF service. Before building our own client to test it, let’s test it with a browser.

To test the RESTful WCF service, first rebuild the solution, then open Internet Explorer and enter the following URL in the address bar of the browser:

http://localhost/RESTNorthwindService/ProductService.svc/Product/5

.

Depending on your browser’s settings, you might be prompted to open/save the response file, or you might get the following content displayed on your browser:

{“Discontinued”:true,”ProductID”:5,”ProductName”: “Chef Anton’s Gumbo Mix”,”QuantityPerUnit”:”36 boxes”,”RowVersion”:[0,0,0,0,0,0,7,252], “UnitPrice”:21.3500}

This shows the JSON-formatted details of the product with ID .

Now if you try to call the

UpdateProduct

method on the browser, you will get a response that says Method not allowed. As this is a

POST

method, we have to create a client to submit a

POST

request to the service…

You can expose the service in two different endpoints.
the SOAP one can use the binding that support SOAP e.g. basicHttpBinding, the RESTful one can use the webHttpBinding. I assume your REST service will be in JSON, in that case, you need to configure the two endpoints with the following behaviour configuration

An example of endpoint configuration in your scenario is

so, the service will be available at

Apply [WebGet] to the operation contract to make it RESTful.
e.g.


public interface ITestService
{
[OperationContract]
[WebGet]
string HelloWorld(string text)
}

Note, if the REST service is not in JSON, parameters of the operations can not contain complex type.

Testing a WCF web service

I have developed a WCF web service for commercial purposes.

I intend to allow someone else to test the service separately from the application that will utilize the web service. This is necessary as we currently do not have access to the app, as it is being developed by a third party.

It’s crucial to keep in mind that the individual I plan to pass this off to for testing is not a programmer.

Are there any tools available that can subscribe to a WCF web service, identify the required data for insertion, and generate a user interface for experimenting with various data combinations?

Thanks.

Solution 1:

For that purpose, I usually utilize SoapUI, which not only allows you to create test suits but is also free. Another option is the Microsoft WcfTestClient.exe, which has been included in Visual Studio since around version 2008.

Solution 2:

wcf test client (WcfTestClient.exe)

The WCF Test Client (WcfTestClient.exe) is located at **C:\Program Files\Microsoft Visual Studio 9.0\Common7\IDE**.

Testing service operations can be done by utilizing the WCFTestClient tool.

Solution 3:

You have the option of utilizing Office InfoPath to access a web service, or creating a straightforward C# test application.

Solution 4:

Typically, it is necessary to release the metadata of the web service (usually as a wsdl endpoint), which should provide all the required information for clients to invoke the web service.

Here is a helpful resource that you might find useful: http://msdn.microsoft.com/en-us/library/ms734765.aspx.

This link may provide information on exposing a WCF-Service with Multiple-Bindings and endpoints. You can find more details here: http://keithelder.net/blog/archive/2008/01/17/Exposing-a- WCF-Service -With- Multiple-Bindings -and-Endpoints.aspx “””.

Update:

According to the comment, it seems that you require individuals who are not programmers to test your service. You are seeking a user interface that allows direct interaction with your web service and can automatically adjust to any modifications. To my knowledge, there is currently no existing solution that fulfills these requirements, although the previous

asmx

services did offer web forms that served this purpose.

score:0

in my experience, you wouldn’t be able to test directly via the browser. instead you should use a wcf test client:

http://msdn.microsoft.com/en-us/library/bb552364(v=vs.110).aspx

what you can do using your browser, is to see if you can reach the wsdl. an example of a wsdl call in a browser:


http://localhost:8080/decisionservice/ws/pretradechecksruleapp/1.0/pretradechecks/1.0?wsdl

score:0

you should add/change the endpoint “binding” attribute to “webhttpbinding” like this:

or

in both cases you have to add:



... ...

notes:

1) you have to add the attribute behaviorconfiguration to the webbinding and add the behavior configuration

2) in the second solution, you have to change the name of the baseaddress because you can’t have two endpoints configured to the same baseaddress (if anyone knows how to do it, please it would help me too)

Browser-Based Testing for WCF Services

The client gave me Comodo Intermediate .cert and Comodo Root .cert certificates, which I installed on my local machine under Intermediate Certification Authorities and Trusted Root Certification Authorities respectively. Additionally, I also installed the X509 Client Certificate .pem under Trusted People Store. To test my locally running web service, I need to emulate a client call. For Firefox users, there are add-ons available such as the Poster add-on for testing web services and add-ons to view JSON.

Example

The following code example shows a service contract created for a service.

// Define a service contract.
[ServiceContract(Namespace="http://Microsoft.ServiceModel.Samples")]
public interface ICalculator
{
    [OperationContract]
    double Add(double n1, double n2);
    // Other methods are not shown here.
}
' Define a service contract.
 _
Public Interface ICalculator
      _
    Function Add(ByVal n1 As Double, ByVal n2 As Double) As Double
    ' Other methods are not shown here.
End Interface

The ServiceModel Metadata utility tool and

Add Service Reference

in Visual Studio generates the following WCF client class. The class inherits from the generic

ClientBase

class and implements the

ICalculator

interface. The tool also generates the

ICalculator

interface (not shown here).

public partial class CalculatorClient : System.ServiceModel.ClientBase, ICalculator
{
    public CalculatorClient()
    {}

    public CalculatorClient(string endpointConfigurationName) :
            base(endpointConfigurationName)
    {}

    public CalculatorClient(string endpointConfigurationName, string remoteAddress) :
            base(endpointConfigurationName, remoteAddress)
    {}

    public CalculatorClient(string endpointConfigurationName,
        System.ServiceModel.EndpointAddress remoteAddress) :
            base(endpointConfigurationName, remoteAddress)
    {}

    public CalculatorClient(System.ServiceModel.Channels.Binding binding,
        System.ServiceModel.EndpointAddress remoteAddress) :
            base(binding, remoteAddress)
    {}

    public double Add(double n1, double n2)
    {
        return base.Channel.Add(n1, n2);
    }
}
Partial Public Class CalculatorClient
    Inherits System.ServiceModel.ClientBase(Of ICalculator)
    Implements ICalculator

    Public Sub New()
        MyBase.New
    End Sub

    Public Sub New(ByVal endpointConfigurationName As String)
        MyBase.New(endpointConfigurationName)
    End Sub

    Public Sub New(ByVal endpointConfigurationName As String, ByVal remoteAddress As String)
        MyBase.New(endpointConfigurationName, remoteAddress)
    End Sub

    Public Sub New(ByVal endpointConfigurationName As String,
        ByVal remoteAddress As System.ServiceModel.EndpointAddress)
        MyBase.New(endpointConfigurationName, remoteAddress)
    End Sub

    Public Sub New(ByVal binding As System.ServiceModel.Channels.Binding,
        ByVal remoteAddress As System.ServiceModel.EndpointAddress)
        MyBase.New(binding, remoteAddress)
    End Sub

    Public Function Add(ByVal n1 As Double, ByVal n2 As Double) As Double
        Implements ICalculator.Add
        Return MyBase.Channel.Add(n1, n2)
    End Function

ServiceModel Metadata Utility Tool

The

ServiceModel Metadata Utility Tool (Svcutil.exe)

is a command-line tool for generating code from metadata. The following use is an example of a basic Svcutil.exe command.

Svcutil.exe 

Alternatively, you can use Svcutil.exe with Web Services Description Language (WSDL) and XML Schema definition language (XSD) files on the file system.

Svcutil.exe 

The result is a code file that contains WCF client code that the client application can use to invoke the service.

You can also use the tool to generate configuration files.

Svcutil.exe 

If only one file name is given, that is the name of the output file. If two file names are given, then the first file is an input configuration file whose contents are merged with the generated configuration and written out into the second file. For more information about configuration, see

Configuring Bindings for Services

.

Important

Unsecured metadata requests pose certain risks in the same way that any unsecured network request does: If you are not certain that the endpoint you are communicating with is who it says it is, the information you retrieve might be metadata from a malicious service.

Debugging Exceptions Thrown by a Client

Many exceptions thrown by a WCF client are caused by an exception on the service. Some examples of this are:

When these types of exceptions occur, the best way to solve the problem is to turn on tracing on the service side and determine what exception occurred there. For more information about tracing, see

Tracing

and

Using the WCF Web HTTP Help Page

The WCF WEB HTTP Help page displays a short description for each operation provided that you specify one using the DescriptionAttribute. This attribute takes a string that contains a short description of the operation it is applied to. For example, the following code shows how to use the DescriptionAttribute to provide a short description.


[OperationContract] [WebGet(UriTemplate="/template1", BodyStyle = WebMessageBodyStyle.Bare)] [Description("Description for GET /template1")] SyndicationFeedFormatter GetTemplate1();

To turn on the WCF WEB HTTP Help page, you must add an endpoint behavior to your service’s endpoints. This can be done in configuration or code. To enable the WCF WEB HTTP Help age in configuration, add an endpoint behavior with a element, set

helpEnabled

to

true

, and add an endpoint and configure it to use the endpoint behavior. The following configuration code shows how to do this.

To enable the WCF Web HTTP Help page in code, add a service endpoint and add a WebHttpBehavior to the endpoint setting HelpEnabled to

true

. The following code shows how to do this.


using (WebServiceHost host = new WebServiceHost(typeof(Service), new Uri("http://localhost:8000/Customers"))) { host.AddServiceEndpoint(typeof(ICustomerCollection), new WebHttpBinding(), ""); host.Description.Endpoints[0].Behaviors.Add(new WebHttpBehavior { EnableHelp = true }); // ... }

The help page is XHTML based with mark-up that identifies the different parts of the page. This enables clients to programmatically access the page using XElement or other XLinq APIs.

Testing a WCF Service with certificates locally

My WCF Service has a method to receive content and it will be used by a client over the internet. The client has provided certificates that have been installed on my local machine as per their instructions.

Comodo Intermediate .cert belongs to the Intermediate Certification Authorities and is also known as Comodo Intermediate.

Under Comodo, navigate to Root .cert and select Comodo Root from the list of Trusted Root Certification Authorities.

The file named Client Certificate with the extension .pem is to be used for the client certificate in the Trusted People Store.

To examine my locally running webservice, I aim to simulate a customer call. I integrated the certificates and appended the ensuing binding to my WCF Service configuration.

I developed a console application for testing purposes and incorporated the subsequent configuration.

As far as I know, I have a server certificate for both testing and production environment. However, to test everything locally and ensure its success, I am unsure if I need to create another server certificate and if so, how can I do it. Is it possible to create it on the same box or should I consider using SOAP UI or any other tool?

Solution:

If you possess a service certificate issued by a formal institution, you may conduct a local test by following the link provided below: https://docs.microsoft.com/en-us/dotnet/framework/wcf/feature-details/ transport-security -with- certificate-authentication When using certificate-based transport security, it is necessary to first establish trust with the server. If a self-signed certificate is desired, PowerShell can be utilized to create the certificate. The following PowerShell command can be referenced for guidance on creating a self-signed certificate.


New-SelfSignedCertificate -DnsName "vabqia864VM" -CertStoreLocation "cert:\LocalMachine\My"

For further information, please refer to the following links: – To configure a new self-signed certificate for PowerShell, visit https://docs.microsoft.com/en-us/powershell/module/pkiclient/new-selfsignedcertificate?view=win10-ps – In order to set up a port with SSL certificate for server side, we need to use SSL certificate for https protocol. If we are using IIS to host, the website binding module will handle this task. More details can be found at https://docs.microsoft.com/en-us/dotnet/framework/wcf/feature-details/how-to-configure-a-port-with-an-ssl-certificate. – For client side, we must provide a client certificate for authentication. Alternatively, we can use endpoint behavior to accomplish this.


ServiceReference1.ServiceClient client = new ServiceReference1.ServiceClient(); client.ClientCredentials.ClientCertificate.SetCertificate(StoreLocation.LocalMachine, StoreName.My, X509FindType.FindByThumbprint, "9ee8be61d875bd6e1108c98b590386d0a489a9ca");

Using the WCF Client

To use the WCF client, create an instance of the WCF client, and then call its methods, as shown in the following code.

// Create a client object with the given client endpoint configuration.
CalculatorClient calcClient = new CalculatorClient("CalculatorEndpoint");
// Call the Add service operation.
double value1 = 100.00D;
double value2 = 15.99D;
double result = calcClient.Add(value1, value2);
Console.WriteLine("Add({0},{1}) = {2}", value1, value2, result);

Dim calcClient As CalculatorClient = _
New CalculatorClient("CalculatorEndpoint")

' Call the Add service operation.
Dim value1 As Double = 100.00D
Dim value2 As Double = 15.99D

I’m getting a 400 bad request error when I try the method mentioned earlier. Could someone confirm if I’m taking the correct approach to test the service? If I’m doing something wrong, please correct me. Any assistance would be highly appreciated. Thank you.

Solution:

The service endpoint requires you to submit a soap message.

Eg


….

To obtain a soap message, one should utilize the service endpoint definition along with appropriate tooling to generate a valid request.

In addition, it is important to note that the endpoint address should not include

?wsdl

. Only the endpoint address should be used for sending data.

Debug a Self-Hosted WCF Service

A self-hosted service is a WCF service that does not run inside IIS, the WCF Service Host, or the ASP.NET Development Server. The easiest way to debug a self-hosted WCF is to configure Visual Studio to launch both client and server when you choose Start Debugging on the Debug menu.

If the WCF service is self-hosting inside or a process that cannot be launched in this manner, such as NT service, you cannot use this method. Instead, you can do one of the following:

  • Manually attach the debugger to the hosting process. For more information, see Attach to Running Processes.

    — or —

  • Start debugging the client, and then step into a call to the service. This requires that you enable debugging in the app.config file. For more information, Limitations on WCF Debugging.

To start both client and host from Visual Studio

  1. Create a Visual Studio solution that contains both the client and server projects.

  2. Configure the solution to start both client and server processes when you choose Start on the Debug menu.

    1. In Solution Explorer, right-click the solution name.

    2. Click Set Startup Projects.

    3. In the Solution

      Properties dialog box, select Multiple Startup Projects.

After you create a service, the next step is to create a WCF client proxy. A client application uses the WCF client proxy to communicate with the service. Client applications usually import a service’s metadata to generate WCF client code that can be used to invoke the service.

The basic steps for creating a WCF client include the following:

  1. Compile the service code.

  2. Generate the WCF client proxy.

  3. Instantiate the WCF client proxy.

The WCF client proxy can be generated manually by using the Service Model Metadata Utility Tool (SvcUtil.exe) for more information see,

ServiceModel Metadata Utility Tool (Svcutil.exe)

. The WCF client proxy can also be generated within Visual Studio using the

feature. To generate the WCF client proxy using either method the service must be running. If the service is self-hosted you must run the host. If the service is hosted in IIS/WAS you do not need to do anything else.

Closing WCF Test Client

You can close WCF Test Client in the following ways:

  • On the File menu, click Exit. Alternatively, in the WCF Test Client main window, click Close. Both of these actions also shut down WCF Service Auto Host and stop the Visual Studio debugging process if WCF Test Client was launched by Visual Studio.

  • Right-click the WCF Service Host icon in the notification area, and then click Exit. This shuts down both WCF Service Auto Host and WCF Test Client and stops the Visual Studio debugging process.

WCF Web HTTP Service Help Page

.NET Framework 4.6.1 provides an automatic help page for WCF WEB HTTP services. This help page lists a description of each operation, request and response formats, and schemas. This functionality is turned off by default. When a user browses to a WCF WEB HTTP service and appends “/Help” on to the end of the URL, for example

http://localhost:8000/Customers/Help

, a help page like the following is displayed.

The user can then click any method listed in the help page and detailed page for that operation is displayed showing more information about the method, including message formats and example responses. The following image is an example of a help page for a method.

Quickest way to check if WCF service is running

I am running a WCF service on my local machine. The service utilizes a specific default port port, but in case that port is already occupied, I assign a port dynamically.

To enhance its discoverability, I included this in the host.


serviceHost.Description.Behaviors.Add(new ServiceDiscoveryBehavior()); serviceHost.AddServiceEndpoint(new UdpDiscoveryEndpoint());

The client needs to establish a connection with the host, attempting the default port initially. If the connection to the service on the default port fails, the client will proceed with the discovery process.

Based on my findings, the discovery process typically lasts between 20 to 30 seconds. Therefore, I would rather skip it unless the host cannot be located on the default port.

What is the fastest method to ascertain whether my host is using the default port?

I considered implementing a strategy where the open timeout is set to 10 seconds on the client, and then performing a try/catch during the opening process. However, this approach still necessitates a 10-second wait.

Solution 1:

Therefore, if your endpoint is incorrect, invoking

client.Open();

will not result in any exceptions being thrown.

In
service called
, I included a method (

IsAlive()

) that returns true. Consequently, I invoke

client.IsAlive();

immediately after opening, and if the endpoint is incorrect, an exception will occur almost instantly.

Solution 2:

To check if the web service is running, you can simply open the URL in a browser.


http://YourService:8000/YourClass/YourMethod

Entering the URL into the browser’s address bar should display the WSDL page if the service is operational, or a 404 error if it is not.

My WCF service is self-hosted, and upon its start, I utilize the following line of code to display the current URL of the service in a DOS window.


Console.WriteLine("HostInterface running on http://" & Domain & ":" & Port & "/Service/Endpoint" )
