为什么返回类型为IdentityUser而不是ApplicationUser？

Question

I have this class

public class ApplicationUser : IdentityUser
{
   public string Email { get; set; }
   public string ConfirmationToken { get; set; }
   public bool IsConfirmed { get; set; }
   ...
}

and in DbContext class this is what I've done

public partial class PickerDbContext : IdentityDbContext
{
    public PickerDbContext():base("DefaultConnection")
    {
    }
    protected override void OnModelCreating(DbModelBuilder modelBuilder)
    {
        base.OnModelCreating(modelBuilder);
        modelBuilder.Entity<ApplicationUser>().ToTable("Users");
        modelBuilder.Entity<IdentityUser>().ToTable("Users");
        modelBuilder.Entity<IdentityRole>().ToTable("Roles");
    }
    //public DbSet<License> Licenses { get; set; }
    ....
}

now when I try to query the Users table in my repository with something like

var user = _db.Users.SingleOrDefault(u=>u.anyfield);

I think it has return type as IdentityUser and not ApplicationUser because when I do u=>u. intellisense option doesn't show the fields from ApplicationUser

What should I do to make the querying in Users table return ApplicationUser type and why is it giving me return type as IdentityUser

Answer 1

Because IdentityDbContext is not a class you defined, and ApplicationUser is a class that you did define. You create ApplicationUser that inherits from IdentityUser. You create a context that inherits from IdentityDbContext. IdentityDbContext exposes DbSet.

If you want the data to come back as ApplicationUser you can do the following:

context.Users.OfType<ApplicationUser>();

You may also be able to do this in your custom DbContext (unverified):

public new DbSet<ApplicationUser> Users { get; set; }

I haven't tested that though.
