Как заинджекать мне для сервиса интерфейс?

Some services are not able to be constructed (Error while validating the service descriptor 'ServiceType: X.Services.Interfaces.ServiceInterfaces.IWishListItemService Lifetime: Scoped ImplementationType: X.Infrastructure.Business.Services.WishListItemService': Unable to resolve service for type 'X.Domain.Interfaces.EFInterfaces.IWishListItemRepository' while attempting to activate 'X.Infrastructure.Business.Services.WishListItemService'.) (Error while validating the service descriptor 'ServiceType: X.Services.Interfaces.ServiceInterfaces.IWishListItemService Lifetime: Scoped ImplementationType: X.Infrastructure.Business.Services.WishListItemService': Unable to resolve service for type 'X.Domain.Interfaces.EFInterfaces.IWishListItemRepository' while attempting to activate 'X.Infrastructure.Business.Services.WishListItemService'.)

Сервис:

public class WishListItemService : IWishListItemService
    {
        private readonly IMapper _mapper;
        private readonly IUnitOfWork _unitOfWork;
        private readonly IWishListItemRepository _wishListItemRepository;
        private readonly IProductDetailsRepository _productDetailsRepository;

        public WishListItemService(IMapper mapper, IUnitOfWork unitOfWork,
            IWishListItemRepository wishListItemService, IProductDetailsRepository productDetailsRepository)
        {
            _wishListItemRepository = wishListItemService;
            _productDetailsRepository = productDetailsRepository;
            _unitOfWork = unitOfWork;
            _mapper = mapper;
        }

Кoнтроллер:

public class WishListItemController : ControllerBase
    {
        private readonly IMapper _mapper;
        private readonly IWishListItemService _wishListItemService;

        public WishListItemController(IWishListItemService wishListItemService, IMapper mapper)
        {
            _mapper = mapper;
            _wishListItemService = wishListItemService;
        }

Зарегистрируй, как и WishListItemService.
Скорее всего где-то в Startup.ConfigureServices

services.AddScoped<IWishListItemRepository, WishListItemRepository>()

embiid, а он реализует интерфейс IWishListItemRepository?

[embiid]

Василий Банников,

public class WishListItemRepository : GenericRepository<WishlistItem>
    public interface IWishListItemRepository : IGenericRepository<WishlistItem>

[Василий Банников]

embiid, WishListItemRepository действительно не реализует IWishListItemRepository.
Попробуй так:

public class WishListItemRepository: IWishListItemRepository, GenericRepository<WishlistItem> {
// ...
}
public interface IWishListItemRepository : IGenericRepository<WishlistItem> {
// ...
}
