I have made changes as you said..But my view is giving the same exception. Please tell what is problem with my view regarding the " correct @model directive"??

//My ViewModel class
 public class OrderViewData
    {
        //
        public List<Order> OrderData { get; set; }
        public List<OrderDetail> OrderDetailData { get; set; }

    }

//My Index() code

 public ActionResult Index()
        {
            OrderViewData orderView = new OrderViewData();
            orderView.OrderData = (from o in db.Orders select o).ToList();
            orderView.OrderDetailData = (from or in db.OrderDetails select or).ToList();

            return View(orderView);
            
        }

// here is my @model directive
@model List<MvcApplication.Models.OrderViewData>

:-(
