In Remoting under .NET, many books are used to use the client and server side to use the example of sharing member or interface. And there is a problem in actual use.

This is convenient to expand your own function, because the code on many books is copied, if the program is separate independent production, only the interface is released, and the practice of Anwei is hard to succeed.
Examples Although it is implemented in a program, there will be no problem in both two programs. You can try themselves.
