Every developer or anyone related to Microsoft would know about the Microsoft Developer Network, aka MSDN. I regularly have an occasional reason to turn to MSDN for information and other essential ingredients in building code. Most recently Microsoft have been active in providing interesting content on all kind of topics — .NET Development, Servers and Enterprise Development, Development Tools and Languages. MSDN Virtual Labs are also available as an RSS feed. Several recent items are particularly interesting, especially for developers already active in or would like to investigate more on related development projects.
