我一直在处理我的客户端安装中挂起的一个奇怪的应用程序。在尝试了几件事后,我得出的结论是,没有转储它就行不通。所以我在挂起时从我的一位客户那里得到了转储。我必须注意,它只发生在我的安装中,而不是我的开发计算机中。
在我的转储中,我看到 SystemEvents.OnUserPreferenceChanged 事件导致我的 UI 线程阻塞等待线程,该线程不再发送消息。
在这里和谷歌搜索后,我发现有些人也遇到了这个问题。我在代码中上下移动,看看我们是否有机会在非 UI 线程上创建了控件或表单,但没有运气。
这是我的 !clrstack

我认为也许使用转储我可以弄清楚在另一个线程上创建的控件是什么,它会给我一个线索。

我唯一看到的是 InsFocusBI.Presentation.Controls.CustomListView 但我没有看到它是在另一个线程上创建的。
有什么建议吗?有人可以给出另一个想法或尝试吗?
谢谢
