Good XMPP/Jabber client library for .NET 3.5 (or 4.0)

Question

What are some good (or the best!) XMPP/Jabber client libraries for .NET 3.5 or 4.0 development?

I have seen a few decent libraries out there, but most of the good ones seem to be built for Framework 2.0.

(If a Framework 2.0 library is still the best, I'm ok with that. I'm just looking for the best libraries for a new project built on 3.5 or 4.0).

Answer 1

This is the one I use agsXMPP and have never had a problem with it although admittedly I don't push it that hard.

Answer 2

Libraries built on the 2.0 framework should work fine in your 3.5 or 4.0 project, or you could recompile them if you want. Jabber-Net seems to work fine in both of those modes.
