我不是 WinDbg 或 SOS 方面的专家，但有人可以帮我解释一下吗？我认为问题不是死锁，而可能是线程失控。我该如何继续。我被困在这一点上。
谢谢!
最佳答案
该列表中有很多前台线程，并且任何仍在运行的前台线程都会阻止 CLR 关闭，即使应用程序没有任何可见窗口(根据 Microsoft 的 docs) .
可以通过 !ThreadState 命令来判断哪些不是后台，例如:
0:000> !threadstate 2b020
Legal to Join
CLR Owns
CoInitialized
In Multi Threaded Apartment
Fully initialized
使用 !threads 输出的 State 列中的值作为参数。
返回列表，所有状态为 2b020 或 202b020 的线程都是前台。检查它们的堆栈，将它们与您在代码中创建它们的位置联系起来。
创建它们时，通过将 IsBackground 属性设置为 true 将它们设置为背景。更好的是，不要创建它们。这是一个很好的替代方案列表:Background Thread? Let me count the ways....
