http://msdn2.microsoft.com/en-us/netframework/aa904594.aspx is one of the most important features in .NET Framework 3.5 (Visual Studio 2008). It's the new way to mapping database tables to classes, and as we know, we call this http://en.wikipedia.org/wiki/Object-relational_mapping. An article on how to write LINQ code quickly is always welcome for beginners, and I think that reading samples is the best way to learn a new technique.

These are samples created while I was learning and using LINQ, and I want to share them now. Hope they will be helpful. I will use Northwind database as a sample, which you can download from the link at the top of this article.

I recommend that you read http://msdn2.microsoft.com/en-us/vcsharp/aa336746.aspx if you would like to learn more.
Also there are good stuff on net
