现象是设置 WPF 开机启动的时候，概率界面不显示，进程已经起来，同时占用内存极小。通过 dump 或附加调试可以看到主进程带等待触摸线程的回应

在我的某个有趣的设备上，这个设备开机启动的时候将会比较慢初始化完成 USB 设备，或者说是 HID 触摸屏设备

此时测试小伙伴告诉我说测试了几百次，会发现有一次某个开机启动的 WPF 应用起不来了

我使用 dnspy 附加调试看到了主线程其实执行了，但是在一个锁里面等待，如下图

实际上的进入锁的代码是没有意义的，需要看是业务上哪里进入了锁

从调用堆栈里面，如下图，可以看到是 PenThreadWorker.WorkerGetTabletsInfo 方法在等待锁

通过 WPF 触摸到事件 可以了解到这是在等待触摸线程执行

这是在 dnspy 断点不够准，实际的代码是 getTablets.DoneEvent.WaitOne();

也就是这个是在等待一个锁，这个会在什么时候释放，会在 Stylus Input 线程执行完成之后释放，那么 Stylus Input 线程在做什么呢

这个 Stylus Input 线程在等待触摸消息，这就有趣了。主线程在等待触摸线程执行获取 Tablet 信息，而触摸线程在等待主线程初始化完成之后可以获取触摸消息

因此主线程等不到触摸线程执行获取触摸信息完成，也就是主线程被锁住

那为什么刚好主线程需要等待触摸获取信息？原因是刚好在开机的时候收到了 OnDeviceChange 消息，因此就会需要调用 WispLogic 的 WispTabletDevices 属性的获取，从本文下方的详细的主线程堆栈可以看到

因此解决方法是禁用 WPF 启动的时候初始化触摸，禁用方法 通过 AppSwitch 禁用 WPF 内置的触摸让 WPF 程序可以处理 Windows 触摸消息 - walterlv

这个解决方法的缺点是会干掉多指触摸，不过没关系，咱可以使用消息解决这个问题。通过监听 Windows 触摸消息加上 WPF 模拟触摸设备 就能继续做多指触摸了
