尝试关闭 DesktopWindowXamlSource 时引发的异常

Exception thrown when attemping to close DesktopWindowXamlSource

本文关键字：异常 DesktopWindowXamlSource      更新时间：2023-10-16

我正在为我的Win32 C++应用程序使用UWP Xaml托管API。我有以下代码：

winrt::Windows::UI::Xaml::Hosting::WindowsXamlManager XamlManager = winrt::Windows::UI::Xaml::Hosting::
WindowsXamlManager::InitializeForCurrentThread();
winrt::Windows::UI::Xaml::Hosting::DesktopWindowXamlSource XamlSource;

当我完成 UWP 内容时，我正在调用

XamlSource.Close();
XamlManager.Close();

但调试器的输出窗口指示正在引发异常：windowsadvcorewinrtiwindowcorewindowdesktopdesktopwindowcontentbridge.cpp(499)Windows.UI.dll!00007FFD91CD860F: (caller: 00007FFD91CD7704) ReturnHr(1) tid(7168) 8007139F The group or resource is not in the correct state to perform the requested operation.

我做错了什么？
