am beginner in ASP.net, just started wintip toy tutorial. I am using Microsoft Visual Studio 2012 for Web. But this tutorial required VS 2013. So kindly guide me
1. VS 2012 for web is valid for this tutorail

2. As i am using VS 2012, so it is not creating Models Folder by default.

3. and there is no Default class IndentityModels.cs in. i am making that class manually but it is giving many errors. i.e

using Microsoft.AspNet.Identity;
   using Microsoft.AspNet.Identity.EntityFramework;
   using Microsoft.Owin.Security;
   using System.Web;
   using System;
   using WingtipToys.Models;

using System.Data.Entity;

namespace WingtipToys.Models
{
    public class ProductContext : DbContext
    {
        public ProductContext()
            : base("WingtipToys")
        {
        }
        public DbSet<category> Categories { get; set; }
        public DbSet<product> Products { get; set; }
    }
}
