Visual Studio 2010 introduces modeling projects that bring UML diagrams to Visual Studio. Currently it is not possible to generate classes from diagrams automatically but I don’t think it is a problem – good UML diagrams visualize different aspects of system short and clearly and they usually don’t document everything you can find in system. In this posting I will show you how to use modeling projects in Visual Studio 2010.

When I started building in-house demo application I thought about how to solve temporary data layer so I don’t have to use real database and object mappings for it. Playing with new object model and new components I move way faster if I don’t have any additional ballast that I can avoid. So I wrote simple cache based repository mechanism I can use to imitate real repositories that I will write in the future.
