Коли я запускаю PM> Remove-Migration -context BloggingContext
VS2015 з проектом ASP.NET Core за допомогою EF Core, я отримую таку помилку:
System.InvalidOperationException: The migration '20160703192724_MyFirstMigration' has already been applied to the database. Unapply it and try again. If the migration has been applied to other databases, consider reverting its changes using a new migration. at Microsoft.EntityFrameworkCore.Migrations.Design.MigrationsScaffolder.RemoveMigration(String projectDir, String rootNamespace, Boolean force)

Як я можу не застосувати це? Я використовую останню версію ASP.NET Core 1.0, EF Core та VS2015 Update 3.
