SessionMenu.Xaml.cs
首先我在代码上面运行，当我点击TrackButtonClick（）事件触发新页面打开但它不起作用时，我的意思是不跟踪骨架。
Exercise.Xaml.cs
First i am running above code, when i clicked on TrackButtonClick() event fire new page open but its not working , i mean not tracking the skeleton.

推荐答案
您必须将在MainWindow上创建的传感器对象传递到练习
窗口。从那里您可以订阅该活动，您无需重新打开。同样，即使关闭窗口以防止内存泄漏，也需要确保取消订阅。
You have to pass the sensor object you created on MainWindow to your Exercise window. From there you can subscribe to the event, and you don't have to re-open. As well, you need to ensure you have unsubscribed from that even when you shutdown the window to prevent memory leaks.
