Inheritance one-to-one or zero relationship with IdentityUser class

Question

This is my Classes :

 public class ApplicationUsers : IdentityUser<Guid>
    {

        [InverseProperty("ApplicationUser")]
        public virtual User User { get; set; }
        [InverseProperty("ApplicationUser")]
        public virtual WorkerTaxi WorkerTaxi { get; set; }

    }

Person Abstract Class :

    public abstract class Person
    {

        [DatabaseGenerated(DatabaseGeneratedOption.None)]
        public Guid PersonId { get; set; }
        ....
    }

User Class :

public class User:Person
    {
        ....
        [ForeignKey("PersonId")]
        [InverseProperty("User")]
        public virtual ApplicationUsers ApplicationUser { get; set; }

    }

And WorkerTaxi Class :

public class WorkerTaxi : Person
    {
        .....
        [ForeignKey("PersonId")]
        [InverseProperty("WorkerTaxi")]
        public virtual ApplicationUsers ApplicationUser { get; set; }

    }

I want to have one to one or zero relationship between ApplicationUsers.cs and User.cs and ApplicationUsers.cs and WorkerTaxi.

When I run this test, it passes without any problem :

                await userManager.DeleteAsync(user: user);

        }

PS.ServiceTest.ApplicationUsersRepositoryTest.Verify_GetAllWorker_Method threw exception: System.InvalidCastException: Unable to cast object of type 'PS.Model.Models.Taxi.WorkerTaxi' to type 'PS.Model.Models.User'.

The error was occurred when await userManager.CreateAsync(user: worker) was ran.

Where is the Problem ?

How can I fix that ?

Update

I found the real problem .... when it tries to add WorkerTaxi to Person table , the discriminator is always 0 base on this code :

public enum AccountType
    {
        User = 0,
        TaxiWorker = 1
    }
  model.Entity<Person>()
                .HasDiscriminator<int>(name: "Type")
                .HasValue<WorkerTaxi>(value: Convert.ToInt32(value: AccountType.TaxiWorker))
                .HasValue<User>(value: Convert.ToInt32(value: AccountType.User));

How can i fix that ?

should the code determine the discriminator or not ?
