You can always get the latest binary package on Nuget or download the binaries as a .zip archive from GitHub. The documentation is also available for offline viewing as HTML or CHM and can be downloaded from here and here, respectively.

To use the library add the Net.Xmpp.dll assembly to your project references in Visual Studio. Here's a simple example that initializes a new instance of the XmppClient class and connects to an XMPP server:

using System;
using Net.Xmpp;
using Net.Xmpp.Client;

namespace Test {
	class Program {
		static void Main(string[] args) {
			/* connect on port 5222 using TLS/SSL if available */
			using (var client = new XmppClient("jabber.se", "username", "password"))
			{
				Console.WriteLine("Connected as " + client.Jid);
			}
		}
	}
}

Please see the documentation for a getting started guide, examples and details on using the classes and methods exposed by the Net.Xmpp assembly.
