LINQ is definitely one of the coolest features in Visual Studio 2008 and the .NET Framework 3.5.  In our June 2007 issue of MSDN Magazine, we ran a couple of feature articles introducing LINQ from the C# and the Visual Basic perspectives.  If you're new to LINQ, or if you're looking for some background into its origins, definitely check these out.  Note, too, that we have some great articles coming out over the next several issues providing deep-dives into some really interesting LINQ-related topics, so stay tuned.
