winform应用在使用一段时间后，切换到其他系统或者打开word、excel文档，再切换回winform应用时，系统有时出现不响应的现象。有时在锁屏后恢复桌面及应用时也发生此问题。
Winform控件会自动订阅系统事件，如果在异步线程中创建UI控件，主线程会通过SynchronizationContext将系统事件同步给其他辅助线程。
但是，如果创建Winform窗体的后台线程没有消息循环处理机制（routinely pumps messages），当UserPreferencesChanged发生时，主线程无法通过SynchronizationContext机制把事件发送到后台线程，因此Hang住。
如下便是问题发生后的dump堆栈，主线程在等待辅助线程的同步消息：

但是当问题发生之后，辅助线程的有效堆栈已经不存在了，如何才能定位到启动异步线程并构造了UI控件的有效堆栈呢？
微软最初的建议是Review关于ThreadPool的代码，但这是有很大难度的：一是代码量很大、肉眼难以有效识别，源代码也是在动态变化的；二是可能有对线程池的封装或变种（BackGroundWorker、System.Threading.Timer、System.Timers.Timer、Task等内部都是通过ThreadPool实现的）；
另外的一个办法就是live debug，但是也存在诸多缺陷（无法稳定重现），每次重启进程后需要重新设置debug跟踪。最后借用辅助代码工具（Freezer），频繁触发UserPreferenceChanged事件，加大出现问题的概率。
Using Windbg to Determine When Windows Forms Controls Are Created
Locate the address of the constructor for System.Windows.Forms.Application+MarshalingControl. We do this using !name2ee along with the module name for the DLL (you can use * to search all modules), and the fully qualified method name.
0:000>!name2ee System_Windows_Forms_ni System.Windows.Forms.Application+MarshalingControl..ctor
Module: 7a981000 (System.Windows.Forms.dll)
Token: 0x060017d8
MethodDesc: 7a99cbcc
Name: System.Windows.Forms.Application+MarshalingControl..ctor()
JITTED Code Address: 7ab46fc0
7ab46fc0 is the address we want to place a breakpoint on. This breakpoint should be hit the first time a Control is created on a thread. It will dump the managed callstack to the output window and then continue on with normal execution.
0:000> bp 7ab46fc0 ".echo MarshalingControl creation detected. Callstack follows.;!clrstack;.echo ==============================;gc"
然而在生产环境很多时候当我们attach到活动进程的时候可能已经晚了，因为异步线程构造UI的代码可能已经执行过了。
所以我们推荐的方式是使用windbg直接启动应用程序，并进入调试状态，此时.net clr、core等DLL尚未加载，还不能load sos.dll。
合适的时机是在加载.NET原生Form的DLL文件时，开始跟踪。实践证明这个方法时有效的。

将此两处的代码做下调整：
1、与显示UI相关的异步操作进行拆分，后台逻辑异步执行，创建UI放到backgroundworker的completed事件中处理（即在主线程创建）
2、以预加载为目的相关的操作，改为new Thread方式，并且将线程运行模式改为STA
经验证后问题修复，Good luck！
