I am often asked for good training material for C#, SQL, and ASP.Net.  My first response is that one of the absolute best sources of Microsoft training, especially recenlty,  is the MSDN website.  MSDN stands for Microsoft Developer's Network.  The URL for the MSDN home page is: http://msdn2.microsoft.com/en-us/default.aspx

If you are a Microsoft developer or technical resource, and don't have this page (or a subpage) set as your Home page in Explorer, hang your head in shame!!!  From this page, you can go to more technology specific home pages, like C#, SQL Server, ASP.Net, etc.

A *fantastic* training resource is the "How Do I" videos.  The URL is: http://msdn2.microsoft.com/en-us/bb629407.aspx
