    public interface IAddTwoNumbers
        // If the asynchronous method pair
        // appears on the client channel, the client can call 
        // them asynchronously to prevent blocking.
        [OperationContract (AsyncPattern=true)]
        IAsyncResult BeginAdd(int a, int b, AsyncCallback cb, AsyncState s);
        int EndAdd(IAsyncResult r);
        // This is a synchronous version of the BeginAdd/EndAdd pair.
        // It appears in the client channel code by default. 
        int Add(int a, int b);
