See for an intro to Facebook.NET, as well as links to other Facebook documentation such as their wiki, main reference pages etc.

i need techanical doc for using the lib

There aren't technical docs per se (at least not yet). The blog entry (which is partially a technical doc) + samples included in the release/source code are meant to complement the Facebook documentation and wiki to get folks started.

The other thing I'd recommend is opening up the assemblies in .net reflector, and viewing the xml doc-comments - all the APIs have been doc'd and that should provide some help as well.

For specific questions, I would recommend asking questions here on this forum.
