public partial class RegistrationController : Controller
{
private readonly IPartnerRepository _partnerRepository;
public RegistrationController(IPartnerRepository partnerRepository)
{
_partnerRepository =partnerRepository;
}}
我使用 autoface 进行依赖注入,但出现此错误:

当我从构造函数中删除时,我没有这个错误:
public partial class RegistrationController : Controller
{
private readonly IPartnerRepository _partnerRepository;
public RegistrationController()
{
}}
我该如何解决这个问题?
