Error: Cannot obtain Metadata from WCF service

I have a successfully running WCF service that I can call using javascript. However I want to invoke it using the WCF test client and im having difficulty doing this. I am told that I need to make sure I have enabled meta data publishing at the specified address. After reading the documentation I just cant see what im meant to do this is my configuration:

    <system.serviceModel>
       <services>
           <service name="CommentSessionIDWCFService" 
                    behaviorConfiguration="CommentSessionIDBehavior">
              <endpoint 
                  address="" 
                  behaviorConfiguration="CountryProvinceBehavior"
                  binding="webHttpBinding" 
                  contract="ICommentSessionIDWCFService" />
           </service>
       </services>
       <behaviors>
          <serviceBehaviors>
             <behavior name="CommentSessionIDBehavior">
                <serviceMetadata httpGetEnabled="true"/>
                <serviceDebug includeExceptionDetailInFaults="true"/>
             </behavior>
          </serviceBehaviors>
          <endpointBehaviors>
              <behavior name="CountryProvinceBehavior">
                  <webHttp/>
              </behavior>
          </endpointBehaviors>
       </behaviors>
    </system.serviceModel>

I've read other posts but I can't see what to populate and I just keep getting errors. Q's..

1. Am I right in saying that I need to configure a complete new service in my config to show the metadata?

2. What do I add to the configuration to make this meta data published so I can invoke with the client?

You need a metadata endpoint for your service, here`s an example.

<services>
    <service name="MyService" behaviorConfiguration="MEX">
    <endpoint
        address="http://localhost:8000/MEX"
        binding="mexHttpBinding"
        contract="IMetadataExchange"
    />
    </service>
</services>

<behaviors>
    <serviceBehaviors>
        <behavior name="MEX">
            <serviceMetadata/>
        </behavior>
    </serviceBehaviors>
</behaviors>

I had a similar problem after changing the config file in the TestClient with right click and "edit with svceditor" to increase my maxbuffersize. If someone did that mistake as well, try rebuilding your project.

Add

[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Required)]

Set httpGetEnabled to true and set the includeExceptionDetailInFaults to false:

<serviceMetadata httpGetEnabled="true"/>

<serviceDebug includeExceptionDetailInFaults="false"/>
