Я пытаюсь добавить миграцию из DatabaseContext
, но когда я добавляю миграцию, я генерирую ее пустой, как это. Я следовал этому уроку
namespace MovieExampleAppDotNetCore.Migrations
{
using System;
using System.Data.Entity.Migrations;
public partial class ModelMigration : DbMigration
{
public override void Up()
{
}
public override void Down()
{
}
}
}
Это модели, Конфигурация миграции, Запуск и DatabaseContext

Я надеюсь, что кто-то может сказать, что я делаю неправильно.
