这是我的课程：
public class ApplicationUsers : IdentityUser<Guid>
{
[InverseProperty("ApplicationUser")]
public virtual User User { get; set; }
[InverseProperty("ApplicationUser")]
public virtual WorkerTaxi WorkerTaxi { get; set; }
}
人抽象类：
public abstract class Person
{
[DatabaseGenerated(DatabaseGeneratedOption.None)]
public Guid PersonId { get; set; }
....
}
用户类：
public class User:Person
{
....
[ForeignKey("PersonId")]
[InverseProperty("User")]
public virtual ApplicationUsers ApplicationUser { get; set; }
}
和WorkerTaxi课程：
public class WorkerTaxi : Person
{
.....
[ForeignKey("PersonId")]
[InverseProperty("WorkerTaxi")]
public virtual ApplicationUsers ApplicationUser { get; set; }
}
我想在ApplicationUsers.cs和User.cs以及ApplicationUsers.cs和WorkerTaxi之间建立一对一或零关系。
当我运行此测试时，它没有任何问题：
[TestMethod]
public async Task Verify_GetAllUser_Method()
{
using (var serviceScope = _serviceProvider.GetRequiredService<IServiceScopeFactory>().CreateScope())
{
var userManager =
serviceScope.ServiceProvider.GetRequiredService<UserManager<ApplicationUsers>>();
var id = Guid.NewGuid();
var applicationUsersService =
serviceScope.ServiceProvider.GetRequiredService<IApplicationUsersRepository>();
//--Arrange
var user = new ApplicationUsers

await userManager.DeleteAsync(user: user);

}

PS.ServiceTest.ApplicationUsersRepositoryTest.Verify_GetAllWorker_Method 抛出异常：System.InvalidCastException：无法转换对象 类型＆＃39; PS.Model.Models.Taxi.WorkerTaxi＆＃39;输入 ＆＃39; PS.Model.Models.User＆＃39;
运行 await userManager.CreateAsync（user：worker）时发生错误。
问题出在哪里？
我该如何解决？
更新
我发现了真正的问题....当它试图将WorkerTaxi添加到Person表时，鉴别器总是0基于此代码：
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));
我该如何解决？
代码是否应该确定鉴别器？
