1105 Media's July 24, 2007 .NETInsight newsletter features my "Layer Data Access with LINQ to SQL" article from the July 2007 issue of Visual Studio Magazine. The feature-length article digs into LINQ to SQL's origins in Microsoft's ill-fated ObjectSpaces project, covers its object/relational mapping (O/RM) features, demonstrates the graphical O/RM designer, and describes the classes that LINQ to SQL autogenerates from SQL Server 200x databases.
The project's sample code is based on Orcas Beta 1, but should be operable with the shortly forthcoming Visual Studio 2008 Beta 2. (Click the "get the code" link under the "Article Tools" heading to download VS0707rj.zip. Requires free registration.)
