Does anyone have any resources where I can learn networking in C#. Right now I only need to know how to deal with TCP in a client server situation. The server needs to be able to support many users at once and handle chat messages. I do have a bit of winsock experience in visual basic and c++. Ive created successful chat programs that support multiple users, and a login server/client so I wont be totally lost here.

Did you try plugging in the appropriate search terms in the MSVC help search, or on MSDN online? There are several samples, in C#, which should help you get going.

i tried for a bit but I didnt find anything.
What did you type in?

I tried C# Networking and .NET Networking.

Try "C# socket example" on MSDN online.

This article has an example of how to write a server in .NET the "right" way. It's slightly advanced, though.
