如何将另一个表添加到具有标识的项目（EF，代码优先）

Question

我有模特"Phone"

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

结束将此模型添加到具有身份的 DBContext：

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

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

接下来，我执行数据库迁移：

dotnet ef migrations add InitialMigration

和：

dotnet ef database update

但是 table "Phones" 没有添加到我的数据库中。我做错了什么？

Answer 1

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