A preview of LINQ, code name for a set of extensions to the .NET Framework that encompass language-integrated data query, set, and transform operations.

• LINQ is a codename for a set of extensions to the .NET Framework that encompass language-integrated data query, set, and transform operations. It includes extensions to the C# and Visual Basic languages with native language syntax for queries and provides class libraries to take advantage of these capabilities.
  
  This package is a combined update of both the VB and C# LINQ Community Technology Previews released in January 2006 and December 2005. It includes samples, whitepapers, hands-on labs and compiler/IDE support for creating LINQ-enabled applications. Major component additions in this release are the DLinq Designer, LINQ over Dataset, Data Binding, and ASP.NET LINQ project templates. For more detailed information, see the readme.
  Note: This is only for testing purposes. Features may change before launch.
