As you can see that from the above screenshot, VS 2010 "Add service reference" adds the standard library class as well. I tried using svcutil and we dont want to use svcutil for a while. Any solution for this ?
For your information : I have used "reuse referenced libraries" and selected only the our own data contract library dll which is shared between wcf and client
Note: In the above GQDPService is the namespace for the service.
