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

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.

Answer 3

Please use MatriX Library for your stuff. The support is really great. Worth it.

Before you buy you could use the trial version and ask for their support in forum.
