EntityFrameWork CodeFirst - Error when Migrating

Question

I am new to MVC ASP.NET and I am currently taking some lectures. But anyway I am trying to migrate to DB using Entity Framework

First my code:

public class ApplicationDbContext : IdentityDbContext<ApplicationUser>
    {
        public DbSet<Customer> Customers { get; set; }
        public ApplicationDbContext()
            : base("DefaultConnection", throwIfV1Schema: false)
        {
        }

        public static ApplicationDbContext Create()
        {
            return new ApplicationDbContext();
        }
    }

Problem is with this line public DbSet<Customer> Customers { get; set; } as when I remove it the migration works fine.

My Customer Class(just couple of properties):

public class Customer : Controller
    {
        public int Id { get; set; }
        public string Name { get; set; }
        public int HouseNum { get; set; }
        public string AddressLine1 { get; set; }
        public string AddressLine2 { get; set; }
        public string Town { get; set; }
        public string PostalCode { get; set; }
        public string Country { get; set; }
    }

Error I receive when running command add-migration InitalModel:

System.NotSupportedException: The type 'System.Web.Routing.RouteCollection+IgnoreRouteInternal' and the type 'System.Web.Mvc.RouteCollectionExtensions+IgnoreRouteInternal' both have the same simple name of 'IgnoreRouteInternal' and so cannot be used in the same model. All types in a given model must have unique simple names. Use 'NotMappedAttribute' or call Ignore in the Code First fluent API to explicitly exclude a property or type from the model.

I checked other posts and people suggest to check names in models. I've done that and there are no repeating names...

Any help would be much appreciated.

Thanks aberforth

Answer 1

The issue looks to be because your Customer class is inheriting from Controller. Can you remove that and try again
