阅读更多关于 Is the Windows.ApplicationModel.LockScreen namespace available for non-kiosk use?

The MSDN documentation for the Windows.ApplicationModel.LockScreen namespace claims that "You can create an app that acts as the lock screen, allowing greater user personalization". I'm interested in creating a custom lock screen for Windows 10 Mobile. However, my quest for further documentation yielded only an article about creating a Windows 10 desktop kiosk app .
