Wow! Great news for developers out there.
Microsoft has just made the [tag]MSDN Library[/tag] available for download free from the web.
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.
It's a massive download - between 450 and 1700MB ... so it's going to take a while!
