[1.1.0-pre3][WindowsPackageType none] How to avoid closing the app?

[sude22]

Hi,
I have a WinUI3 nonpackaged app.
How could I prevent the app from closing if the user clicks the X?
In UWP you could register to
SystemNavigationManagerPreview.GetForCurrentView().CloseRequested +=
but thats not working in WinUI3 nonpackaged app.

You can use AppWindow.Closing Event
(args.Cancel = true; to prevent closing)
