У меня есть этот контроллер, как вы можете видеть:
namespace Web.Front.Controllers
{
public class CarController : Controller
{
ICarService _CarService;
public CarController(ICarService carService)
{
_CarService = carService;
}
// GET: Car
public ActionResult Index()
{
return View();
}
}
}
Когда я вызываю действие index, я получаю эту ошибку:
No parameterless constructor defined for this object.

Как примечание, я использую ninject для внедрения сервисов в контроллеры. Когда я удаляю сервис из конструктора, он работает.
Код объекта:
private static void RegisterServices(IKernel kernel)
{
kernel.Bind<DidbaanContext>().To<DidbaanContext>();
kernel.Bind<ICarService>().To<CarService>();
kernel.Bind<ICarRepository>().To<CarRepository>();
}
