My goal was to to make a simple MessageInspector so that I can see what message is going out at some point and probably add some info into the headers at the client side. Now the SDK had quite a good sample of the message inspector implementation but I was looking for something like a hello world.
The point is how you tie up following.
1. Add a custom behavior to the proxy endpoint.
2. Add the IClientMessageInspector to the behavior in the ApplyClientBehavior of the custom behavior
3. Implement the BeforeSendRequest or AfterRecieveReply to get the message
Do provide your inputs on how this can be better used.
