요청을 처리하는 동안 처리되지 않은 예외가 발생했습니다. ASP .NET Core

ASP .net 코어를 처음 사용합니다. 그것은 다음과 같이 종속성 주입 오류를 발생시킵니다.

InvalidOperationException : 'SpinIt.Web.Controllers.CartController'를 활성화하는 중 'Spinit.Data.Services.Repository.GameRepository'유형의 서비스를 분석 할 수 없습니다.

StackTrace는 다음과 같습니다.

CartController 코드

public class CartController:Controller
{
    private readonly GameRepository _gameRepository;
    private readonly Cart _cartRepository;

    public CartController(GameRepository gameRepository, Cart cartRepository)
    {
        _gameRepository = gameRepository;
        _cartRepository = cartRepository;
    }

    public ViewResult Index()
    {
        var items = _cartRepository.GetCartItems();
        _cartRepository.CartItems = items;

        var sCVM = new CartViewModel
        {
            Cart = _cartRepository,
            CartTotal = _cartRepository.GetCartTotal()
        };
        return View(sCVM);
    }
}

Startup.cs 에도 서비스를 추가했습니다

services.AddScoped<IGame, GameRepository>();
services.AddScoped<ICartItem, CartItemRepository>();
