I am new to mocking and dependency injection and need some guidance.
My application is using a typical N-Tier architecture where the BLL references the DAL, and the UI references the BLL but not the DAL. Pretty straight forward.

Recently I've noticed myself implementing pattern similar to the one described below. Starting with interface:
public interface IUserProvider
{
