IIS Hosting - (WCF)

Windows Communication Foundation (WCF) is a framework for building distributed applications that run on a variety of Microsoft platforms. When hosting a WCF service, one option is to use Internet Information Services (IIS) as the host.

Syntax

To host a WCF service in IIS, you will need to create a WCF service project, configure it for IIS hosting, and publish it to an IIS website. Here is an example of how to configure a WCF service for IIS hosting:

<system.serviceModel>
  <services>
    <service name="MyService">
      <endpoint address="" binding="basicHttpBinding" contract="IMyService" />
      <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
    </service>
  </services>
  <behaviors>
    <serviceBehaviors>
      <behavior>
        <serviceMetadata httpGetEnabled="true" />
        <serviceDebug includeExceptionDetailInFaults="false" />
      </behavior>
    </serviceBehaviors>
  </behaviors>
</system.serviceModel>

Example

Here's an example of how to host a WCF service in IIS using a basicHttpBinding:

using System.ServiceModel;

namespace MyService
{
  [ServiceContract]
  public interface IMyService
  {
    [OperationContract]
    string GetData(int value);
  }

  public class MyService : IMyService
  {
    public string GetData(int value)
    {
      return "You entered: " + value;
    }
  }
}

<system.serviceModel>
  <services>
    <service name="MyService">
      <endpoint address="" binding="basicHttpBinding" contract="MyService.IMyService" />
    </service>
  </services>
  <behaviors>
    <serviceBehaviors>
      <behavior>
        <serviceMetadata httpGetEnabled="true" />
      </behavior>
    </serviceBehaviors>
  </behaviors>
</system.serviceModel>

Output

When you deploy your WCF service to IIS, you should see the service hosted at the specified URL. For example, if you set the service address to "http://localhost/MyService", you should be able to access the service by navigating to "http://localhost/MyService" in your web browser.

Explanation

In the example code, we define a simple WCF service that implements the IMyService interface. The service has a single method, GetData, which takes an int parameter and returns a string message. We then configure the service to use a basicHttpBinding and define the service endpoint as the IMyService interface. We also configure the service metadata to be enabled for HTTP GET requests, which allows clients to access the service's metadata.

Use

IIS hosting is a commonly used option for WCF services, as it provides robust hosting capabilities and can be easily integrated with other web applications. IIS hosting allows you to take advantage of the performance and scalability benefits of IIS, while also providing the rich feature set of WCF.

Important Points

• When hosting a WCF service in IIS, you will need to create a WCF service project, configure it for IIS hosting, and publish it to an IIS website.
• You can use a variety of bindings and protocols to configure your WCF service for IIS hosting.
• IIS hosting allows you to take advantage of the performance and scalability benefits of IIS, while also providing the rich feature set of WCF.
