如何获取Windows 10应用商店应用程序的进程ID /句柄?

Question

我有现有的代码库，它在应用程序启动时返回应用程序的句柄。它适用于所有应用程序。但是每次我打开任何商店应用程序时，无论是计算器，闹钟还是Skype。我收到应用程序框架主机的句柄，而不是特定应用程序的句柄。 但是，如果我使用 win32Api 查询句柄的窗口标题，我会得到特定的应用程序名称。

为什么我得到的是ApplicationFrameHost而不是Skype的句柄。有没有办法从ApplicationFrameHost Handle获取Skype的句柄？

这是一个开始。 只需添加您的 GetWindowText(( 等...逻辑。
