问题
Folks,
I hit the following exception and I know for a fact that its not a timeout issue and that its a message size issue. Using ONLY the CommunicationException, is there a way to tell that this issue was a message size issue and not a timeout issue? Perhaps one of the properties on CommunicationException? or maybe it can be cast in a certain way? I'm willing to explore any proposals.
System.ServiceModel.CommunicationException: The socket connection was aborted. This could be caused by an error processing your message or a receive timeout being exceeded by the remote host, or an underlying network resource issue. Local socket timeout was '24.11:30:00'. ---> System.IO.IOException: The read operation failed, see inner exception. ---> System.ServiceModel.CommunicationException: The socket connection was aborted. This could be caused by an error processing your message or a receive timeout being exceeded by the remote host, or an underlying network resource issue. Local socket timeout was '24.11:30:00'. ---> System.Net.Sockets.SocketException: An existing connection was forcibly closed by the remote host

There doesn't seem to be a good way to do this.
