LINQ, Entity Framework, and Project Astoria by Jonathan Carter
Last night I attended the Sarasota .NET Developers Group monthly meeting and got to hear another great talk by Jonathan Carter (who has also spoken at the Tampa and Jacksonville code camps recently). Most of the talk was spent on LINQ, starting off with LINQ to Objects and then building from there into LINQ to SQL, and even more impressively, LINQ to Entities (and the Entity Framework).
As I've been using LINQ for a little while now (and since I've already heard an earlier talk by Jonathan on that subject in Tampa, Florida), I didn't think I would learn much more on that subject. But of course, I did.
You can see some samples, and my "take" on that talk here: http://www.singingeels.com/Blogs/Nullable/2007/09/20/LINQ_Entity_Framework_and_Project_Astoria_by_Jonathan_Carter.aspx
