Summary

This Wrox Blox demonstrates various LINQ to SQL techniques to use in upgrading the "Articles" portion of TheBeerHouse application. The first step is migrating TheBeerHouse project from an ASP.NET 2.0 to an ASP.NET 3.5 application. Next, create a LINQ to SQL class (DBML) mapping file that will encapsulate the entire Data Access Layer for this project. Readers will become comfortable working with Entities (Tables), navigating Associations (Relationships), and working with stored procedures from a LINQ standpoint, throughout the implementation. LINQ to SQL has quickly become a hot topic with the release of ASP.NET 3.5, so it makes sense that the TheBeerHouse application gets an upgraded Data Access Layer leveraging this new technology! While TheBeerHouse has been ported to Visual Basic .NET, the author uses C# throughout this Wrox Blox, so readers should have at least an intermediate level of understanding with C#.
