与mvvmcross错误UWP + xamarin形成

Question

I，M试图导航到一个xamarin形成了另一个观点+ mvvmcross与

public ICommand GoCommand 
    { 
     get 
     { 
      return new MvxCommand(() => ShowViewModel<SecondViewModel>()); 
     } 
    } 

安卓工作正常，但UWP崩溃（“错误HRESULT E_FAIL已从返回调用COM组件“）Show方法：

public async void Show(MvxViewModelRequest request) 
    { 
     if (await this.TryShowPage(request)) 
     { 
      return; 
     } 

     Mvx.Error("Skipping request for {0}", request.ViewModelType.Name); 
    } 

任何想法？提前致谢！

好!!我已经看到了我的错误。我需要添加该代码

 var start = Mvx.Resolve<IMvxAppStart>(); 
     start.Start(); 

方法结果：

public MainPage() 
    { 
     this.InitializeComponent(); 

     var start = Mvx.Resolve<IMvxAppStart>(); 

     start.Start(); 

     MvxFormsWindowsUniversalViewPresenter presenter = Mvx.Resolve<IMvxViewPresenter>() as MvxFormsWindowsUniversalViewPresenter; 

     if (presenter == null) 
     { 
      return; 
     } 

     this.LoadApplication(presenter.XamarinFormsApp); 
    }
