public class MvcApplication : Ninject.Web.Mvc.NinjectHttpApplication
{
    public static void RegisterGlobalFilters(GlobalFilterCollection filters)
    {
        filters.Add(new HandleErrorAttribute());
    }

    public static void RegisterRoutes(RouteCollection routes)
    {
        routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

        routes.MapRoute(
            "Default", // Route name
            "{controller}/{action}/{id}", // URL with parameters
            new { controller = "Home", action = "Index", id = UrlParameter.Optional } // Parameter defaults
        );

    }

    protected void Application_Start()

    protected override IKernel CreateKernel()

ServiceModule.cs

internal class ServiceModule : NinjectModule

    }
}

public class MyDependencyResolver : IDependencyResolver

    }

    public System.Collections.Generic.IEnumerable<object> GetServices(System.Type serviceType)
    {
        return kernel.GetAll(serviceType);

    }
}

public interface IGreetingService
{
    string Hello();
}

public class GreetingService : IGreetingService
{
    public string Hello()
    {
        return "Hello from GreetingService";
    }
}

public class TestController : Controller
{

    private readonly IGreetingService service;

    public TestController(IGreetingService service)
    {
        this.service = service;
    }

    public ActionResult Index()
    {
        return View("Index", service.Hello());
    }
