Question

我正在asp.net mvc应用程序中工作。我对依赖注入使用unity。到目前为止，我已经将所有依赖项注入了UnityConfig.cs（dbcontext，存储库，webservice）中，并且一切正常。添加了身份框架以提供身份验证。我想在帐户控制器中注入一些依赖性，该控制器是Identity用于登录和注册操作的控制器，但是我无法使其工作。有人遇到过同样的问题吗？

AccountController.cs

public AccountController(IMyRepository myRepository, ApplicationUserManager userManager, ApplicationSignInManager signInManager)
        {
            MyRepository = myRepository;
            UserManager = userManager;
            SignInManager = signInManager;
        }

UnityConfig.cs

container.RegisterType<AccountController>(new InjectionConstructor());
container.RegisterType<IMyRepository, MyRepository>();
