I want to create my own binding class, a class that inherits System.ServiceModel.Channels.Binding (or one of its subclasses). Does anyone know any good articles or have any tips on how to do this?
The binding I want to create should offer the same functionality as WsDualHttpBinding, i.e. server to client communication, but without requiring the client to listen on any port. I have already achieved server to client communication trough BasicHttpBinding, thanks to Ian Griffiths http://discuss.develop.com/archives/wa.exe?A2=ind0409A&L=ADVANCED- DOTNET&P=R3331&I=-3 The idea behind this technique is this: The client calls a GetMessage operation at the server asynchronously and the server handles the call asynchronously. The server waits until a given timeout before it responds by sending null back. When the client receives the null response, it immediately calls GetMessage again. At any given time, the server may want to call the client. It does so by letting the GetMessage operation return immediately (without waiting for the timeout), and letting the message be the return value of the GetMessage operation. The client handles the returned message as if it was an incoming call. The advantage of this technique is that it does not require the client to listen to any port, and that it does not require the server to wait for the next poll before being able to send information to the client, as normal polling would do. As mention, I have succeeded making the communication work. What I want now is to hide the logic in the Binding. Any tips will be greatly appreciated!
