A Windows Communication Foundation (WCF) service has the following contract.
[ServiceContract(Namespace=”http://contoso.com”)]
public interface IShipping
{
[OperationContract]
string DoWork(int id);
}
This is one of several service contracts hosted by your application. All endpoints use SOAP 1.2 bindings with WS-Addressing 1.0. The System.ServiceModel.MessageLogging trace source in the system.diagnostics configuration section is configured with one listener.
You need to make sure that only the messages that are returned from the DoWork operation are logged.
Which XML segment should you add to the system.serviceModel/diagnostics/messageLogging/filters configuration element?
