I am working on a Windows MAUI application. Simply: I have a database, from which I load data upon app opening, and I want to save the new data when the app is closed.

What I am currently doing:

protected override Window CreateWindow(IActivationState? activationState)
{
    Window window = base.CreateWindow(activationState);

    window.Destroying += OnAppWindowDestroying;

    return window;
}

private async void OnAppWindowDestroying(object? sender, EventArgs e)
{
    await Task.Delay(2000); // Database write operation goes here
}

The issue:
The app process is terminated before the database operations are terminated and my data are not persisted. So it seems I am not using the correct approach.

I also tried using Windows specific event like so:

    .ConfigureLifecycleEvents(events =>
                {
#if WINDOWS
                    events.AddWindows(windows => windows
                    .OnClosed(async (window, args) => await Task.Delay(2000)// database write operation goes here );
#endif
                });

I guess the question is:

Is there anyway to delay a Windows App closing ? If not, then what is the correct way to perform a database operation upon app closing, launching a new process ?

Thanks for some insight here
