Question

I'm new to dtonet. I created repository and injected it into controller but got this error in controller constructor

Inconsistent accessibility: parameter type 'IContactRepository' is less accessible than method 'ContactController.ContactController(IContactRepository)'

Answer 1

You'll have to set IContactRepository as public in the file it is defined.

public interface IContactRepository {
  ...
}
