MS Edge 的组件 WebView2 在关闭时使 C++ 应用程序崩溃 window
MS Edge's component WebView2 crashes C++ application on closing window
MS Edge runtime: 94.0.992.31
Nuget package : Microsoft.Web.WebView2 1.0.992.28
我们有两个解决方案：托管 C++ 应用程序和 Wpf GUI 库。
在托管 C++ 中，我们使用 wpf 的视图。
我们使用旧 System.Windows.Controls.WebBrowser 时一切正常。没有崩溃。但是，好吧，渲染 HTML 变得更复杂，更难在旧控件中正确渲染。因此，经过一些调查，我们决定使用 Microsoft 的顶部边缘控制。当我们只测试 WPF GUI 项目时，一切都很好。
我们非常高兴和兴奋它有多好。
然后当我们尝试将更新的视图集成到 C++ 应用程序时，出现了问题。如果用户从带有托管 WebView2 控件的适当 window 菜单中选择 -> 它会成功显示所有必要的内容。渲染非常复杂的东西真的很棒 html/css。
但是，当用户单击关闭相应 c++ window（托管带有集成 WebView2 组件的 wpf 视图）的“十字”按钮时，它会立即冻结整个应用程序，并在几秒钟后应用程序崩溃。日志是空的，它崩溃得太快以至于应用程序无法在日志中做任何记录。
您能否提供一些关于如何找到解决方法的想法...？
更新：
我已经在 C++ 应用程序中订阅了来自 WPF
的 Application.DispatcherUnhandledException 事件
void CMainFrame::OnDispatcherUnhandledException(System::Object^ sender, System::Windows::Threading::DispatcherUnhandledExceptionEventArgs^ e)
{
System::String ^ expMessage = e->Exception->ToString();
}
它提供以下错误消息
System.InvalidOperationException: 释放WebView2控件后无法访问CoreWebView2成员。 System.Runtime.InteropServices.COMException: 组或资源未处于执行请求操作的正确状态。 （HRESULT 异常：0x8007139F）
它看起来很奇怪，因为 window 已关闭，我们不会尝试再次打开它。
这是一个调用堆栈：
System.InvalidOperationException: CoreWebView2 members cannot be accessed after the WebView2 control is disposed. ---> System.Runtime.InteropServices.COMException: The group or resource is not in the correct state to perform the requested operation.

我对这个问题做了一些相关的搜索，发现这是一个已知问题。运行时94.0.988.0+似乎受到影响，请参考这个案例：Process crashed after app started.
所以这从代码上看似乎无法解决问题，所以如果现在需要解决问题，可能需要安装以前版本的Edge Dev，或者等待Edge更新。

我对这个问题做了一些相关的搜索，发现这是一个已知问题。运行时94.0.988.0+似乎受到影响，请参考这个案例：Process crashed after app started.
所以这从代码上看似乎无法解决问题，所以如果现在需要解决问题，可能需要安装以前版本的Edge Dev，或者等待Edge更新。
