Wcf Duplex Callback problem RRS feed

  • Question

  • Hi folks, I'm currently trying to develop a duplex service using a WCF Service and a silverlight client. Up till yesterday everything worked out just fine. Today however I added a new method to my service, nothing fancy. So .. cleaned the service ... rebuild => "Warning 1 Custom tool warning: Request/Reply callback contracts are not supported in Silverlight". Suddenly all Callback events are missing from the generated client class. I undid the code changes, removed the method, but still no luck, the warning persists and I can't figure out how to reverse the service into it's previous state. Any suggestions ?

  • I solved my dilemma, one cannot use the IsOneWay Attribute set to false .. as in having methods that have return values, somehow this method did not affect the client generationtool svcutil.exe the first time, now it does.
