Cannot create controller with Entity framework - Unable to retrieve metadata

c# entity-framework visual-studio-2013

Question

I'm using VS2013

When I try to create an "MVC 5 Controller with views using entity Framework" I get the following error:

there was an error running the selected code generator ''Unable to retrieve metadata for WebApplication.Domain.Entities.Product'.'

EFDbContext.cs

using System.Data.Entity;
using WebApplication.Domain.Entities;

namespace WebApplication.Domain.Concrete
{
    public class EFDbContext : DbContext
    {
        public DbSet<Product> Products;
    }
}

Product.cs

using System.ComponentModel.DataAnnotations;

namespace WebApplication.Domain.Entities
{
    public class Product
    {
        [Key]
        public int ProductID { get; set; }

        [Required]
        public string Title { get; set; }
    }
}

Web.config

<?xml version="1.0" encoding="utf-8"?>

      <provider invariantName="System.Data.SqlClient" type="System.Data.Entity.SqlServer.SqlProviderServices, EntityFramework.SqlServer" />
    </providers>
  </entityFramework>
</configuration>

I have a Table set up called Products and it has a definition like so:

CREATE TABLE [dbo].[Products] (
    [ProductID] INT            IDENTITY (1, 1) NOT NULL,
    [Title]     NVARCHAR (255) NULL,
    PRIMARY KEY CLUSTERED ([ProductID] ASC)
);

Any ideas what is going wrong? I have tried everything that has returned on Google.

Packages I have installed:

<?xml version="1.0" encoding="utf-8"?>
<packages>
  <package id="EntityFramework" version="6.0.1" targetFramework="net45" />
  <package id="jQuery" version="1.10.2" targetFramework="net45" />
  <package id="jQuery.Validation" version="1.11.1" targetFramework="net45" />
  <package id="Microsoft.AspNet.Mvc" version="5.0.0" targetFramework="net45" />
  <package id="Microsoft.AspNet.Razor" version="3.0.0" targetFramework="net45" />
  <package id="Microsoft.AspNet.WebPages" version="3.0.0" targetFramework="net45" />
  <package id="Microsoft.jQuery.Unobtrusive.Validation" version="3.0.0" targetFramework="net45" />
  <package id="Microsoft.Web.Infrastructure" version="1.0.0.0" targetFramework="net45" />
  <package id="Unity" version="3.0.1304.1" targetFramework="net45" />
  <package id="Unity.Mvc" version="3.0.1304.0" targetFramework="net45" />
  <package id="WebActivatorEx" version="2.0.4" targetFramework="net45" />
</packages>

Problem may be because of missing [NotMapped] Attribute in one of the model class.

As I missed the attribute and I was cunning my head.

[Display(Name="Logo")]
[DataType(DataType.Upload)]
[NotMapped]
public HttpPostedFileBase Logo { set; get; }
