For the first time, we're making the MSDN Library freely available for download from Microsoft Downloads. Previously, the Library was only available for download to MSDN subscribers. The current download is the May 2006 Edition and future editions will also be available when we release them.

 

MSDN Library provides access to essential programming information, including technical white papers, software development kits and code samples necessary to develop web services and applications. This is an updated version of the MSDN Library for Visual Studio® 2005.
