Appfabric WF4-WCF services, how to retrieve current url in codeactivity without httpcontext?

You need to implment IReceiveMessageCallback and add that to an activity's context. In the OnReceiveMessage you get passed the current OperationContext allowing you to inspect the incoming message.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
