C# \ VB .net Multi-user communication library (TCP) - CodeProject

Introduction

The NetComm library allows you to connect multiple clients to the same server. This allows you to do the following:
- Transfer personal messages to each other
- Send a message to all of the users in the same server (public messages)
- Communicate with each client using only ID (a unique string), without the need of knowing each other IP, the clients only need to know the host IP address.
The NetComm library handles all of the complicated work, it works in a separate thread from your application UI - the NetComm library will raise an event when a new message arrived.
Why is this useful? Well, this allows you to create a multi-user chat easily - or any other kind of application that needs to handle multiple users communication.
