creating controller doesn't work

I'm learning asp.net mvc3 from w3schools and following that tutorial.http://w3schools.com/aspnet/mvc_models.asp In the section "ASP.NET MVC Models" I have created the model like this.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Data.Entity;

namespace MvcDemo.Models
{
    public class MovieDB
    {
        public int ID { get; set; }
        public string Title { get; set; }
        public string Director { get; set; }
        public DateTime Date { get; set; }
    }

    public class MovieDBContext : DbContext
    {
        public DbSet<MovieDB> Movies { get; set; } 
    }
}

Then I was going to add a controller according to the instructions.

In the Solution Explorer, right-click the Controllers folder, and select Add and Controller Set controller name to MoviesController
Select template: Controller with read/write actions and views, using Entity Framework
Select model class: MovieDB (McvDemo.Models)
Select data context class: MovieDBContext (McvDemo.Models)*
Select views Razor (CSHTML)
Click Add

But the problem I have is that the drop down list doesn't show MovieDB (McvDemo.Models) in Model Class and Data Context Class to be selected. Can anyone please help me? Thanks.

Solution

You should just be able to recompile (Shift-Ctrl-B) and then try it again - it will be there. Otherwise you can always just declare it yourself at the top of a blank view, but that will not provide the scaffolding that the generator does:

@model MvcDemo.Models.MovieDB;
