Examples

The following code example shows how to use a configuration file to enable the HTML help page feature and return exception information inside a SOAP fault back to the client for debugging purposes. This configuration file shows the following basic steps to adding support for the ServiceDebugBehavior features:

Because the ServiceDebugBehavior type is a System.ServiceModel.Description.IServiceBehavior implementation, the <service> element that represents the service type has a behavior configuration identifier of behaviorConfiguration="metadataAndDebug".
Again, because the ServiceDebugBehavior type is an System.ServiceModel.Description.IServiceBehavior implementation a <behavior> element is added to a <serviceBehaviors> section. The name attribute of the <behavior> element the value of which is the identifier of the behaviorConfiguration attribute of the <service> element. In this case, the value is metadataAndDebug.
Add a <serviceDebug> element with the various attributes set to the desired configuration. In this case, the httpHelpPageEnabled and includeExceptionDetailInFaults attribute values are set to true.

<configuration>
  <system.serviceModel>
    <services>
      <!-- 
        Step 1. Add a behaviorConfiguration attribute
        in the <service> element.
      -->
      <service 
        name="Microsoft.WCF.Documentation.SampleService"
        behaviorConfiguration="metadataAndDebug">
        <host>
          <baseAddresses>
            <add baseAddress="http://localhost:8080/SampleService" />
          </baseAddresses>
        </host>
        <endpoint
          address=""
          binding="wsHttpBinding"
          contract="Microsoft.WCF.Documentation.ISampleService"
        />
        <endpoint
           address="mex"
           binding="mexHttpBinding"
           contract="IMetadataExchange"
        />
      </service>
    </services>
    <behaviors>
      <serviceBehaviors>
        <!-- 
          Step 2. Inside a <serviceBehaviors> section, add 
          a name attribute in the <behaviors> element that 
          matches the behaviorConfiguration attribute in the
          <service> element above.
        -->
        <behavior name="metadataAndDebug">
          <serviceMetadata 
            httpGetEnabled="true" 
            httpGetUrl=""
          />
          <!-- 
            Step 3. Add a <serviceDebug> element and 
            modify the various attributes that suit your 
            scenario.
          -->
          <serviceDebug 
            httpHelpPageEnabled="true" 
            includeExceptionDetailInFaults="true"
          />
        </behavior>
      </serviceBehaviors>
    </behaviors>
  </system.serviceModel>
</configuration>

Remarks

Set the HttpHelpPageEnabled property to false to disable the publication of an HTML help page visible to HTML browsers.

To ensure the HTML help page is published at the location controlled by the HttpsHelpPageUrl property, you must set this property to true and then one of the following conditions must also be true:

The HttpsHelpPageUrl property is an absolute address that supports the HTTP protocol scheme.
There is a base address for the service that supports the HTTP protocol scheme.

Although an exception is thrown if an absolute address that does not support the HTTP protocol scheme is assigned to the HttpsHelpPageUrl property, any other scenario in which neither of the preceding criteria is met results in no exception and no HTML help page.
