У меня проблема с тем, что EF Core не позволяет мне добавить мою вторую миграцию. У меня есть следующие настройки DataContext:
public class DataContext : IdentityDbContext<User, Role, Guid, IdentityUserClaim<Guid>, UserRole, IdentityUserLogin<Guid>, IdentityRoleClaim<Guid>, IdentityUserToken<Guid>>
{
public DataContext(DbContextOptions<DataContext> options)
: base(options)

Поэтому, когда я изначально создал свою первую миграцию, я использовал следующее:
Add-Migration "Initialization" -o "Data\Migrations"
Но каждый раз, когда я пытаюсь чтобы добавить вторую миграцию, когда я хочу добавить новые поля в таблицу, я получаю эту ошибку, говорящую, что Value cannot be null (Parameter: Key)
public class Audit
{
[Key]
[DatabaseGenerated(DatabaseGeneratedOption.Identity)]
public Guid Id { get; set; }
public Guid GroupId { get; set; }
[ForeignKey(nameof(GroupId))]
public Group Group { get; set; }
public Guid UserId { get; set; }
[ForeignKey(nameof(UserId))]
public User User { get; set; }
public int AuditTypeId { get; set; }
[ForeignKey(nameof(AuditTypeId))]
public AuditType AuditType { get; set; }
public string IP { get; set; }
public string BrowserInfo { get; set; }
public string OriginalObject { get; set; }
public string UpdatedObject { get; set; }
public DateTime CreationTime { get; set; }
**public string TestField { get; set; }**
}
Кто-нибудь имеет представление о том, почему я ' я не могу добавить эту вторую миграцию? Показанная ошибка:

Насколько я понимаю, у нас есть поле ключа, которое инициализируется нулем, поэтому оно не может создать новую миграцию, но я не могу найти, где эта проблема исходит от. Самое странное, что первая миграция работает правильно.
Любая помощь будет принята, спасибо, ребята!
