Duwamish Books is also an electronic commerce application. However, the key focus is that Duwamish Books has been implemented in both Visual Basic .NET as well as Visual C# .NET. The focus isn't performance metrics, though, but on flexibility for developers to utilize their own preferred programming language (in this case, C# or Visual Basic .NET). Duwamish Books is an n- tier application developed using ASP.NET, Managed Components, and ADO.NET DataSets using SQL Server Data Provider. The current version, 7.0, is an evolution of the existing Duwamish Books sample that had been developed using multiple architectures earlier. Key best practices demonstrated here are the extensive use of Stored Procedures, Business Fa §ade, Business Rules, and ASP.NET Output caching.
