Override Exit method on App.xaml.cs

[rossirpaulo]

How can we override the Exit method on WinUi3? I want to have a reliable way to perform some tasks before the program ends. Note that there is a way to override the OnLaunch method by:

    protected async override void OnLaunched(LaunchActivatedEventArgs args)

Is there something similar for closing/terminating the application?

Main is overridable.
For C#, if you look for the generated App.g.i.cs file then you can work out how to do this. Make sure that it does everything that the currently defined main does.

It is usually done on AppWindow.Closing

It's closed in WinUI3 microsoft/microsoft-ui-xaml#5454

closed is for Microsoft.UI.Xaml.Window
and cancel allows to intercept closing
