Opening a dialog in the event handler of AppDomain.CurrentDomain.UnhandledException is not possible,

[ahakMiethke]

I am trying to show the user a dialog when the app crashes with an UnhandledException to improve user experience. However, it seems that this is not working as intended. Can someone guide me on how to do that?

This is a dummy code of how i am trying to do it

AppDomain.CurrentDomain.UnhandledException += (sender, args) =>
            {
                var mainPage = Microsoft.Maui.Controls.Application.Current?.MainPage;
                Microsoft.Maui.Controls.Application.Current?.Dispatcher.Dispatch(async void () =>
                {
                    await mainPage.DisplayPromptAsync("title", "message", "cancelButton");
                });
            };

It seems like not terminating the app is not possible on ios, but on android you can look at this example #653 (comment)

When AppDomain.CurrentDomain.UnhandledException is triggered, the app will terminate no matter what and doing any UI stuff is not supported at that level. However, the event mentioned above is triggered only when a debugger is attached. If the app is executed without a debugger, the Android.Runtime.AndroidEnvironment.UnhandledExceptionRaiser event will be triggered and we can stop the app from terminating and do any logic as we wish.
