Where to start to build .NET Multiuser Chat Application?

Hello,

Which .NET namespaces should I be looking at if I'd like to start writing a very simple chat application (in C#)?

Please let me know if there's a way that I can clarify or expand on this to make it a more precise question.

Thanks,

Adam
