Start working on Sample Application, this's about my idea of how to set up basic Application infrastructure. Basically, Main Web Application has Web, Logic, Data Layer, all of them has its shared project.
so far, trying to add Source(Src), UnitTest and Library(Lib), it might be more in one solution
add xml check box will generate xml for your dll, which able to see xml comment
This structure helps, if Framework team can focus on working on Shared Solution, Actual, Web Solution can work on its own project too.
