I am Exposing BizTalk Orch as a WCF service.
Both my incoming and outgoing messages are of type System.String.
I can get in and work with the incoming message without a problem.
The problem begins when I send out the response.
The service returns null no matter what string I send.
I have tried sending back a strongly typed message and that works fine, the problem is with sending a message of type System.String. I'm guessing it may be some type of encoding issue.
Any Ideas?
