Creating an Instante Messenger using XMPP and C#.NET

Hello

I've been trying to create an Instant Messaging application in my ASP.NET site using C#. I came to know about XMPP which is a protocol used for instant messaging by GChat. I was wondering how to implement it in my ASP.NET application. Any insights provided on this will be very much appreciated.

Thank you.

The thing about the C# libraries is that most of them are closed-source or licensed. I've found MatriX (used to be agsXMPP) to be the best in terms of what it can do (developer license might be a bit steep though). Jabber.net would probably be a good choice too.

It's not for the faint of heart. Building out a client might be ok but building a component or deploying a server caused me no end of headaches. Understanding how it works first might be the best approach. There is a book called "XMPP: The Definitive Guide" that I found really useful.

You are right about the licensing and pricing of the available libraries. As you said i need to go in and out of the technology to build a component.

You might not have to, it depends on what you want to implement. If it's just chat, I think you will be ok with just choosing a server and using BOSH. If you are trying to push messages from your application through XMPP then you will need to delve into the component side.A note about the Javascript book recommended below: I purchased it, but had to give up almost immediately as I couldn't get any of the code to actually work. The author didn't reply to the forum posts about it until a few months later, but I still had problems. YMMVSee the thread here:http://tinyurl.com/3xscwl4

Does this book deal with creating and deploying an XMPP server?
