Getting Started With LINQ To SQL(转)

原文地址:http://dotnet.org.za/hiltong/archive/2008/02/20/getting-started-with-linq-to-sql.aspx

Considering I've put a few posts up about LINQ To SQL, I realised I've never shared some of the initial links I passed to other team members as well. If you're looking into using this technology, here are some worthwhile links to follow. Some are tutorials, some are tools, some are just worthwhile pieces to understand with this new technology. Also, some are more general LINQ-related than LINQ To SQL specifically.

Essential Reading
