如何使用Ninject注入相同的类实例？

Question

我正在使用Ninject for IoC。我有以下课程。

// Repository
public class EFProductRepository : IProductRepository, IUnitOfWorkRepository
{
  private IUnitOfWork unitOfWork;
  private EFDbContext efDbContext;

  public EFProductRepository(IUnitOfWork uow)
  {
    unitOfWork = uow;
    efDbContext = new EFDbContext();
  }
  //
}

// Controller
public class ProductController : Controller
{
  private IUnitOfWork unitOfWork;
  private IProductRepository productRepository;

  public ProductController(IUnitOfWork uow, IProductRepository repo)
  {
    unitOfWork = uow;
    productRepository = repo;
  }
}

目前我的ninject绑定如下所示，为接口分配具体类的新实例。

ninjectKernel.Bind<IUnitOfWork>().To<UnitOfWork>();
ninjectKernel.Bind<IProductRepository>().To<EFProductRepository>();

使用我的ninject控制器工厂，我需要将相同的IUnitOfWork类实例注入ProductController和EFProductRepository。请指导我。
