System.Net.Sockets Namespace () has the tools you need for socket programming. For example you can use TcpClient/TcpListener for TCP protocol, or UdpClient for UDP protocol. You can find much help in documentation and also by searching web.

You might like to check out this example that uses the asynchronous methods exposed by the TcpClient and TcpListener classes:

[VB2008/.NET 3.5] Asynchronous TcpListener & TcpClient

In that case the server is a Windows application too but, in a real-world scenario, a server would most likely not be a Windows app or a Console app, but rather a Windows service. In my example I have used asynchronous methods at both the client and server ends but, in your case, your server at least will have to be synchronous, e.g. call AcceptTcpClient rather than BeginAcceptTcpClient. Using synchronous methods is simpler than using asynchronous methods, but asynchronous methods provide more flexibility in certain situations.
