Solution
|- Core: Domain models + validering, repository- og/eller service-interfaces.
|- Infrastructure: Repositories og/eller services. Alt der har med I/O at gøre (databaseopslag, kald til web services eller andre RPC'er, skrivning eller læsning af filer).
|- Web: Controllers, Views, opsætning af services, konfigurering af IoC

Hertil kommer et testlag. Det kan være en separat solution med et projekt pr. lag, det kan være ét testprojekt, eller det kan være et testprojekt pr. lag.
