Look your view is expecing a Model:

@model IEnumerable<Models.Web.Category>

In your Controller you're not passing anything to the view, so the view has null as a Model. You need to create your collection IEnumerable<Category> and pass it to the view.

I mean something like this:

public ActionResult Category(){

    var categories = db.Categories;

    return View(categories);

}

OR

 public ActionResult Category(){

    List<Category> categories = new List<Category>();
    categories.Add(new Category() { ID = 1, Name = "Bikes" });
    categories.Add(new Category() { ID = 2, Name = "Cars" });
    categories.Add(new Category() { ID = 3, Name = "Trucks" });

    return View(categories);

}

You should initialize your model in controller...

Model is null.

If you want to display data from the model, you need to pass a model from the controller.
