I can't load Identity User using EF core 2.2

asp.net-core asp.net-identity c# entity-framework-core


I'm building a system where I have the Order entity in which each one has a Sender. I'm using

  • ASP.Net core 2.2 (with Identity for managing the membership);
  • EF core 2.2.

The problem I'm facing is that I can't add the user entity using .Include(x => x.Sender). It is always returned as null.

This is the Order code:

public class Order
    public int Id { get; set; }
    public OrderStatusType CurrentOrderStatus { get; set; }
    public string PublicOrderId { get; set; }
    public Address PickupAddress { get; set; }
    public Address DropAddress { get; set; }

    public User Sender { get; set; }
    public User Receiver { get; set; }
    public User Creator { get; set; }

    public double ExpectedDistance { get; set; }
    public int ExpectedDuration { get; set; }

This is the User code:

public class User : IdentityUser
    public string FirastName { get; set; }
    public string LastName { get; set; }
    public string LastNumber { get; set; }
    public string Gander { get; set; }
    public Language PrefairdLanguage { get; set; }
    public string Themapnail { get; set; }
    public Address DefaultAddress { get; set; }
    public Store Store { get; set; }
    public int Imei { get; set; }

This is the DbContext code:

public class MandoobContext : IdentityDbContext<User>
   // private readonly string connectionString;

    public MandoobContext(DbContextOptions<MandoobContext> options) : base(options)


    protected override void OnModelCreating(ModelBuilder modelBuilder)


    public DbSet<Order> Orders { get; set; }
    public DbSet<Address> Addresses { get; set; }    

This is the controller where I try to retrieve the data from the DB:

public async Task<IActionResult> Order(int id)
    Order order = _context.Orders
        .Include(x => x.DropAddress)
        .Include(x => x.PickupAddress)
        .Include(x => x.Sender)
        .FirstOrDefault(x => x.Id == id);

    return View(order);

Thanks in advance for the help if anyone has an idea.

Are you sure the Sender is set on the database on the given Order? I've created a working application with the VS .net template and added your model to it and it just works.
