Answer 1

Thank Ivan Stoev's answer. i add some more code to easy to imagine. this is code of seed data function base on example.

• First adding data of User.
• After that add data of owned object.
• Data of owned object have to be anonymous because PK will request. This PK will not appear in database. Name should be entity name + Id

Example: Entity XXX => PK will be XXXId

private void SeedUser(ModelBuilder builder)
{
    builder.Entity(b =>
    {
        b.HasData(new User
        {
            Id = "37846734-172e-4149-8cec-6f43d1eb3f60",
            Email = "foo@foo.foo",
            UserName = "foo@foo.foo",
            // more properties of User
        });
        b.OwnsOne(e => e.EmailPermissions).HasData(new 
        {
                UserId = "37846734-172e-4149-8cec-6f43d1eb3f60",
                Newsletter = true,
                PromotionalOffers = true,
                PrestationReminders = true,
                PrestationOffers = true
        });
    });
}
