如何添加另一个表到具有标识的项目（EF，代码优先）

Question

I have a Model "Phone"

public class Phone
    {
        [Key]
        public Guid Id { get; set; }
        public string NameModel { get; set; }
        [MaxLength(100)]
        public int SerialNumber { get; set; }
    } 

End add this model to DBContext with Identity:

public class AppDbContext : IdentityDbContext<AppUser>
    {
        public AppDbContext (DbContextOptions<AppDbContext> options)
            : base(options)
        {
            Database.EnsureCreated();
        }

        public DbSet<Phone> Phones { get; set; }
    }

Next, I perform the database migration:

dotnet ef migrations add InitialMigration

and:

dotnet ef database update

But table "Phones" is not added to my database. What am I doing wrong?

Answer 1

EnsureCreated and Migrations don't work well together. If you're using Migrations, don't use EnsureCreated to initialize the schema.
