ASP .Net błąd połączenia z bazą danych

Question

Hej, podczas tworzenia prostej strony która ma za zadanie wyświetlić z bazy danych liste filmów.

Ale po kompilacji wyskakuje błąd:

Chyba brakuje Ci w Startup

services.AddScoped<IFilmRepositiores, FilmRepositiores>();

 

Ps. A tu masz chyba buga:

        public ActionResult Details(int id)
        {
            return View(_filmotekaRepositiores.Get(1));
        }

//powinno raczej być
        public ActionResult Details(int id)
        {
            return View(_filmotekaRepositiores.Get(id));
        }
