MessageBox result closes application

[UranusDarkness]

I'm trying to use the AdonisUI.Controls.MessageBox for my AutoUpdater, but even though the result is true in the if statement, the code keeps going on until the OnExit event. For example: I click on Yes when it asks me to update, and instead of showing the Window, it closes the application

 messageBox = new MessageBoxModel{
                            Text = $@"There is new version {args.CurrentVersion} available. You are using version {args.InstalledVersion}. Do you want to update the application now?",
                            Caption = @"Update Available",
                            Icon = AdonisUI.Controls.MessageBoxImage.Information,
                            Buttons = MessageBoxButtons.YesNo(),
                        };

                        AdonisUI.Controls.MessageBox.Show(messageBox);

if (messageBox.Result.Equals(AdonisUI.Controls.MessageBoxResult.Yes) || messageBox.Result.Equals(AdonisUI.Controls.MessageBoxResult.OK)) {
                        try
                        {
                            if (Models.AutoUpdater.DownloadUpdate(args))
                            {
                                AutoUpdateWindow autoUpdateWindow = new AutoUpdateWindow();
                                autoUpdateWindow.Show();
                            }

                        }
                        catch (Exception exception)
                        {
                            AdonisUI.Controls.MessageBox.Show(exception.Message, exception.GetType().ToString(), AdonisUI.Controls.MessageBoxButton.OK, AdonisUI.Controls.MessageBoxImage.Error);
                        }
                    }

It seems like it closes the application because I don't have an active window at that moment, since I'm using them in App.xaml. Is there a way to do so?

[UranusDarkness]

New update: by debugging several times, I discovered that when it calls autoUpdateWindow.Show(), it raises the OnExit event of the App.xaml Still looking for a way to fix this tho

I'm not sure this is specific to AdonisUI. This can happen when opening/closing a dialog when you don't have a main window open. Your best bet would be to enable explicit shutdown using the Application.Shutdown property: https://docs.microsoft.com/en-us/dotnet/api/system.windows.shutdownmode?view=windowsdesktop-6.0#system-windows-shutdownmode-onexplicitshutdown
