ThumbnailToolBarButton을 사용하여 창에서 닫기 닫기를 호출 할 수 없습니다.

Question

ThumbnailToolBarButton을 클릭하면 새로운 WPF 응용 프로그램에서 창을 닫으려고합니다 (기본 생성 된 xaml에 대한 변경 사항 없음). 나는 그렇게하려고하면, 나는 다음과 같은 오류가 표시 오전 :

using System; 
    using System.Reflection; 
    using System.Windows; 
    using System.Windows.Interop; 
    using Microsoft.WindowsAPICodePack.Taskbar; 

    namespace WpfApplication1 
    { 
     /// <summary> 
     /// Interaction logic for MainWindow.xaml 
     /// </summary> 
     public partial class MainWindow : Window 
     { 
      public MainWindow() 
      { 
       InitializeComponent(); 

       Loaded += new RoutedEventHandler(MainWindow_Loaded); 
      } 

      void MainWindow_Loaded(object sender, RoutedEventArgs e) 
      { 
       ThumbnailToolBarButton thumbCancel = new ThumbnailToolBarButton(System.Drawing.Icon.ExtractAssociatedIcon(Assembly.GetEntryAssembly().Location), "Cancel"); 

       thumbCancel.Click += new EventHandler<ThumbnailButtonClickedEventArgs>(thumbCancel_Click); 

       TaskbarManager.Instance.ThumbnailToolBars.AddButtons(new WindowInteropHelper(this).Handle, thumbCancel); 
      } 

      void thumbCancel_Click(object sender, ThumbnailButtonClickedEventArgs e) 
      { 
       Close(); 
      } 
     } 
    } 

감사 :

아마도 WPF 아래에서 Win32 창을 삭제할 것입니다.

쉽게 시도 할 준비가되어 있지 않지만 Close() 호출을 BeginInvoke() 호출로 변경하면 닫기가 트리거되어 thumbCancel_Click에서 처리하고 Close at을 처리 할 수 ​​있습니다. 적절한 시간.
