I have found a workaround for this problem. This website solved me quite a few problems before, so I thought it would be nice to share back.
You can use just plain HttpWebRequest to do this. I think it will need to be POST service operation (as GET would assume some response, but since you declare it as void it would have no response). In which case Execute can't be used anyway (as it always issues a GET request).
Using plain HttpWebRequest just issue a simple POST to the service operation URL and just check the response status code (should be 204 No Content). Currently WCF Data Services doesn't have native client support for service operations, so you need to write one for yourself.
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.
