repository-pattern

I am new to repository pattern but i tried, my goal is to make a design which will let me easily with just some few edits "dependency injection, or configuration edits" to be able to switch to another ORM without touching other solution layers.

I have an ASP.NET MVC application which uses Entity Framework to get data. I need to transform Entites to Models before passing them to View.
