.NET 3.5 SP1 LINQ improvements

In May, I announced the changes related to LINQ that were included in .NET 3.5 Service Pack 1 Beta. Now that the SP1 is officially available, more changes have been announced.

The originally announced changes were:

1. The support for SQL Server 2008
2. The release of a new flavor of LINQ: LINQ to Entities, which comes with the ADO.NET Entity Framework
