Northwind.NET

Northwind sample database, shipped with any Access version, shows different programming techniques, so Access developer can take look at sample code and quickly learn it. Northwind.NET does the same for .NET framework – it is a set of sample applications demonstrating various modern technologies and development practices used within .NET Framework and Visual Studio 2008. If you once need to make something in .NET – just look at this project, find a type of form or report you want to build and check how you can build it using different .NET development techniques.

Plus - there is a sample of calling .NET web service from Access (or wrapping any .NET class into COM)!
