Seed entity with owned property

Question

I am trying to seed an user entity in my database. The User entity has an owend property EmailPermissions.

When I run the command

Answer 1

In my scenario I wanted the owned-type property to be auto-initialed in the parent class:

public class User
{
  EmailPermissions _EmailPermissions;
  public EmailPermissions 
  {
    get => _EmailPermissions ??= new EmailPermissions();
    set => _EmailPermissions = value;
  }
}

When I tried to add seed data I got that nasty exception.

The solution was to pass the User as anonymous type in its HasData call.
