.Net Remote problem

Question

Dear All, I was build a remote object to speedup the client size program, here are some question to ask! 1. How to add the remote reference into Visual Studio project file (client size). I can compile the code with /r under dos enviroment, but when I add it into the project file and compile by VS, seems it will go back to run the local object. 2. Which is a best way to protect my code (server size). Thank's for help
