Question

I have a HomeController and a Referrence of a type-class.If I create a new object of the class it works fine for me. But I dont want to create new object in the Controller instead I want to pass a referrence of the class through the HomwController’s Constructor.Here is my code. I need to implement DI here.

//private readonly UnitOfWork<Student> _unitOfWork = new UnitOfWork<Student>();
    private readonly UnitOfWork<Student> _unitOfWork;

    //TODO ??
    public HomeController(UnitOfWork<Student> unitOfWork)
    {
        _unitOfWork = unitOfWork;
    }

    public ActionResult Index()
    {


        return View(_unitOfWork.GenericRepository.GetAll());
    }

Any help?

Are you talking ASP.NET MVC ?

I have been working with Ninject for some time now, and am very happy with it! Take a look at the sample app in this repository to get an idea on how to use it in ASP.NET MVC 3:

https://github.com/ninject/ninject.web.mvc/tree/master/mvc3

To expand a bit on the reply, here’s a code snippet from where I set up the Ninject bindings

kernel.Bind(typeof(IUnitOfWork<>).To(typeof(UnitOfWork<>));

And my controller:

public class MyController : Controller {
    private readonly IUnitOfWork<Student> uowStudent;
    public MyController(IUnitOfWork<Student> uowStudent) {
        this.uowStudent = uowStudent;
    }
}

Then all you need to do, is make sure any arguments in the constructor for the UnitOfWork class are also bound in the kernel.
