This means your DI container is trying to construct a StudentsController, and it cannot seem to find a registration for your UnitOfWork class (or any of its dependencies).

Make sure the UnitOfWork class (or better: the interface it implements) is registered in your DI of choice, along with all other referenced interfaces/classes.

EDIT: After looking at your code, you're missing a registration for the AirlineContext. Furthermore, you're newing stuff (the AirlineRepository in UnitOfWork) while you're using DI.

I can't help but get the feeling you haven't completely understood this yet...
