LINQ/DLINQ release available for download
An updated version of LINQ (including DLINQ) for Whidbey (Visual Studio 2005) RTM is avilable for download from Microsoft.
LINQ is the Language Integrated Query which provides a syntax for querying over collections and database tables with a SQL-like syntax integrated right into your favorite .NET language. DLINQ is the "lightweight" ORM (Object-Relational Mapper) that will translate your query into a database query to return data back to your application from the database.
