How to send private messages with Facebook API using C#

[glendacerise]

I use Facebook Connect for login on my website and need to create functionality of sending personal messages to user's Facebook friends.A solution from http://stackoverflow.com/questions/2574431/facebook-api-send-private-messages-to-friends and Connect to facebook chat using Jabber.net (C#/Mono) with SASL). I hope to find some existing solution instead of updating one of these libraries. Or to find some library like xmpp4r_facebook but for .NET platform. Thanks.
