I already included the ServiceB proxy dll as reference to ServiceA.
As you mentioned I added the using declaration as:
but still doesn't work.
I only can suspect for now is that the reference cannot access to ServiceBOperations for some reason which I don't know.
There is no problem with compiling and running ServiceB, so I don't know what makes the problem.
Let me check again what I've been fallowing.
I added fallowing code
serviceb.ServiceBOperations _servicebPort = null;
in just right below :
public class SercieAService : DsspServiceBase
under Robotics.ServiceA namespace
Thanks for help,
