Turn on IncludeExceptionDetailInFaults (either from ServiceBehaviorAttribute or from the configuration behavior) on the server

Question

I have a WCF service that has been working perfectly, and something has changed and I don\'t know what.

I get this exception:

System.ServiceMo

If you want to do this by code, you can add the behavior like this:

serviceHost.Description.Behaviors.Remove(
    typeof(ServiceDebugBehavior));
serviceHost.Description.Behaviors.Add(
    new ServiceDebugBehavior { IncludeExceptionDetailInFaults = true });
