Answer 1

It's a bit late, but for other users here is a better approach (in my opinion) and the code above only has to be changed a little bit

You can change:

    public class WcfErrorServiceBehaviour : IServiceBehavior

to:

    public class WcfErrorServiceBehaviourAttribute : Attribute, IServiceBehavior

Now you can use this as an attribute for your service-class like this:

    [WcfErrorServiceBehaviour]
    [ServiceBehavior(InstanceContextMode = InstanceContextMode.PerCall,
                     ConcurrencyMode = ConcurrencyMode.Multiple)]
    public class MXServiceCommands : IMXServiceCommands
    {
    }

Hope this helps some others.

<system.serviceModel>
  <behaviors>
    <serviceBehaviors>
      <behavior>
        <!-- To avoid disclosing metadata information, set the value below to false and remove the metadata endpoint above before deployment -->
        <serviceMetadata httpGetEnabled="true" />
        <!-- To receive exception details in faults for debugging purposes, set the value below to true.  Set to false before deployment to avoid disclosing exception information -->
        <serviceDebug includeExceptionDetailInFaults="true" />
        <errorHandler/>
      </behavior>
    </serviceBehaviors>
  </behaviors>
  <serviceHostingEnvironment multipleSiteBindingsEnabled="true" />
  <extensions>
    <behaviorExtensions>
      <add name="errorHandler" type="CustomerWcfService.WcfErrorHandlerBehaviour, CustomerWcfService, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null"/>
    </behaviorExtensions>
  </extensions>
</system.serviceModel>

And then apply your behavior to the service you want it to be applied to.

Edit :

sorry for the miss, but you actually need to remove any line-break and any additional white space in the type name in the extension definition (old WCF bug which force you to use the fully qualified name string in extension type declaration).
