Process.HasExited为true但进程仍然存在

Question

在等待某个进程退出时，我发现当进程仍然存在于任务管理器中时，Process.HasExited为true，而Process.WaitForExit（0）返回false。知道为什么吗？

这个问题与Process.HasExited returns true even though process is running?不同，因为在那个问题中，WaitForExit返回true。

它看到退出进程在global-destruct上抛出异常，可能导致调试对话框打开。 （因为原因，在我的环境中无法看到它）所以这个过程是半死的？退出但没有退回？

在进程上调用CloseMainWindow（）然后我等待它退出。主窗口确实关闭了。但这个过程仍然没有退出。

从调试器添加对象的转储 请注意，signaled为false，hasExitTime为false，ExitCode返回异常。 Just HasExited是真的。
