What is Repository Pattern in ASP.NET MVC?
Repository pattern is usefult for decoupling entity operations form presentation, which allows easy mocking and unit testing.
“The Repository will delegate to the appropriate infrastructure services to get the job done. Encapsulating in the mechanisms of storage, retrieval and query is the most basic feature of a Repository implementation”
“Most common queries should also be hard coded to the Repositories as methods.”
Which MVC.NET to implement repository pattern Controller would have 2 constructors on parameterless for framework to call, and the second one which takes repository as an input:

class myController: Controller

{

    private IMyRepository repository;

 

    // overloaded constructor

    public myController(IMyRepository repository)

    {

        this.repository = repository;

    }

 

    // default constructor for framework to call

    public myController()

    {

        //concreate implementation

        myController(new someRepository());

    }

...

 

    public ActionResult Load()

    {

        // loading data from repository

        var myData = repository.Load();

    }

}
