I also saw you used a "StaticResource" in there....depending on where that desired
resource is in your chain of dictionaries, you may need to use DynamicResource.

private static IntPtr WndProc(IntPtr hwnd, int msg, IntPtr wParam, IntPtr lParam, ref bool handled)
{
  const WM_QUERYENDSESSION = 0x0011;
  switch (msg)
  {
    case WM_QUERYENDSESSION:
      // The "screen" is fading here - do what you need to do...
      break;
  }
  return IntPtr.Zero;
}

void MyWindow_Loaded(object sender, RoutedEventArgs e)
{
  HwndSource src = HwndSource.FromHwnd(new WindowInteropHelper(this).Handle);
  src.AddHook(new HwndSourceHook(WndProc));
}
