How to implement Unit of work in MVC: Responsibility

Question

Who has the responsability

---

Who has the responsibility to start and finish the Unit of work in a MVC architecture?

Answer 1

I am a believer in loosely coupled architecture. My controller knows NOTHING about the repository, context or unitofwork. I have created a service layer (not sure that is the right term) that the controller calls. This service then works with the repository (dll) to persist all data.
