Jason Gaylord has a post on how to Obtain the Identity of a New Row Using LINQ:

Dim db As New BlogDataContext()
db.BlogPosts.InsertOnSubmit(MyPost)
db.SubmitChanges()
Dim IdentityValue As Integer = MyPost.PostID

Frans Bouma releases LINQ support for LLBLGen Pro.

1. The Basics
2. From and Select
3. DISTINCT, WHERE, ORDER BY, and Operators
4. Functions
5. GROUP BY and HAVING
6. Joins
7. UNION, TOP, and Subqueries
8. LEFT-, RIGHT-OUTER JOIN
9. FULL OUTER JOIN

Beth Massi posts about how to create lookup lists with LINQ to SQL.

Alex Miller asks, "Is LINQ leaving Java in the dust?"

He goes on to say that Java is still OK, but he focuses on libraries that try to accomplush something like LINQ.  The part that he isn't recognizing is that LINQ is Language INtegrated Query.  It isn't able the libraries, it is about the language integration.

Don Burnett has a great list of some of the LINQ tools currently on CodePlex.  Some of the ones I'm going to dive into are:

• LINQ to JavaScript
• LINQ to Amazon's SimpleDB
• LINQ to Lucece
