I saw the .NET Tiers generator a while ago, and I think it looks very interesting. From the looks of it, you come up with a database, take their templates, load them in CodeSmith, and you can generate just about everything else: Your stored procedures, your DAL, your entities, and even web services to expose it all. Oh yeah - a Visual Studio project and solution too. And unit tests.

All you need is a UI. If it works, this would make development a lot quicker.
