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.

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.
