Charlie Calvert's LINQ posts

Charlie Calvert, who some of you may know for the years he spent at Borland or for his books on Delphi, joined Microsoft in July as the Community Program Manager for the Visual C# group.
Charlie has a blog full of C# and .NET community information. As part of his activities, he started a series of posts on LINQ:

1. LINQ for Beginners
2. Query Expressions
3. Query Operators
4. Using Distinct
5. Focus on Grouping

Another great source of knowledge if you want to explore LINQ. 

Charlie also collected a list links about LINQ: Links to LINQ.
