Help in MULTIPLAYER GAME IN .NET

Sir i am a newbie in programming field. I wanna create a multi-player network based Poker Card game as my B.tech project. I google alot and created a client-server chat app as a part of the game. Now i am really confused how to proceed further. I dpn't know how server works in a multi-player game. Should i create more then one server (one for chat interaction between the players and other for handling the game status). I Have no idea what to do. Even though there are no tutorials available on Net which can help me throughout the stages of my project. Should i better take coaching or what should i do? Please help me. I have done a basics course in .NET(C#, winforms,webapplication) and developed many websites in .NET. But have no idea about networking 😔 . Please help me.
