MVC 3 Controller Unit Testing - TryUpdateModel and a few kinds of exception

I ran into serious problem while testing my Controller in ASP.NET MVC 3.0.

Here is one of the controller's methods:

    public ActionResult Create(FormCollection collection)
    {
        IModel model = null;
        model = modeldao.createNewObject(ref model);
        TryUpdateModel(model, null, null, new[] { "id" });
        ... // rest
    }

The most important par开发者_如何学编程t of the test for method mentioned before is written just like that

Controller controller = new Controller(// list of mocks)
FormCollection form = new FormCollection();
form.Add("name", "object1");
form.Add("parentobject.id", "1");
controller.ValueProvider = form.ToValueProvider();
controller.Create(form);

For now, it throws ArgumentNullException, even if I mock ControllerContext object. When I try to set ValueProvider property in controller:

controller.ValueProvider = form.ToValueProvider();

then I get MethodAccessException and I'm told to add new assembly: System.ComponentModel.DataAnnotations.

I have already read a few articles about testing MVC 3 Controller (there's not plenty of them), but their tips simply do not work, though code seems to be similar:

I would like to ask if someone has ever encountered this kind of problem and solved it.
