        // Add custom user claims here

public class ApplicationDbContext : IdentityDbContext<ApplicationUser>
{
    public DbSet<CardModel> Cards { get; set; }
    public DbSet<Banners> Banner { get; set; }
    public DbSet<Category> Category { get; set; }

    public ApplicationDbContext()
        : base("DbConnection", throwIfV1Schema: false)
