c# C# Networking

[KomaWei]

I'm trying to find a network library in C# that supports Proxy, SSL and Async. UPnP would be nice also. I'm not willing to spend money on a professional commercial library.

This do?

Already looked at. It didn't offer proxy support, nor did it offer SSL.

There is literally so many to choose from... failing that you could put together one in ~4-6hours...

The _WebRequest classes should support proxies already as well.

Lidgren is designed for UDP game sockets. I'm guessing you're looking for web communication?

Check out SuperSocket:

Well, more like chat clients, etc. Not really web communication.

Have you looked at the TcpClient and TcpListener classes? They're very easy to use and have a function to get a stream object you can use for sending and receiving data.

What's wrong about System.Net.WebClient?

It supports Proxy - if I'm not mistaken it even uses whatever settings Windows is currently using by default.

It supports SSL - you can even add your own code to support self-signed or other certificates that would normally fail the security check

It supports Async both upload and download.

for UPnP you can look at NATUPnP which is shipped with windows (howto here: http://pietschsoft.com/post/2009/02/05/NET-Framework-Communicate-through-NAT-Router-via-UPnP.aspx )
