    New process/exe from a switch?

    I am new at this, but I've been following along with this video: https://www.youtube.com/watch?v=0Wcn-ZK9mi4

    I have an OK understanding of what is going on in the code below and marked where I believe I should launch the app. The problem is, I am not sure what to use. I have read that I can use Sytem.Diagnostics.Process.Start but that doesn't seem to work; Can anyone help a newbie out?

    I realize I am in over my head but I am having fun and learning as I go; any help is greatly appreciated!

    Code:
    sealed partial class App : Application
    {
    
    
        /// <summary>
        /// Initializes the singleton application object.  This is the first line of authored code
        /// executed, and as such is the logical equivalent of main() or WinMain().
        /// </summary>
        public App()
        {
            this.InitializeComponent();
            this.Suspending += OnSuspending;
        }
    
        /// <summary>
        /// Invoked when the application is launched normally by the end user.  Other entry points
        /// will be used such as when the application is launched to open a specific file.
        /// </summary>
        /// <param name="e">Details about the launch request and process.</param>
        protected async override void OnLaunched(LaunchActivatedEventArgs e)
        {
    #if DEBUG
            if (System.Diagnostics.Debugger.IsAttached)
            {
                this.DebugSettings.EnableFrameRateCounter = true;
            }
    #endif
            Frame rootFrame = Window.Current.Content as Frame;
    
            // Do not repeat app initialization when the Window already has content,
            // just ensure that the window is active
            if (rootFrame == null)
            {
                // Create a Frame to act as the navigation context and navigate to the first page
                rootFrame = new Frame();
    
                rootFrame.NavigationFailed += OnNavigationFailed;
    
                if (e.PreviousExecutionState == ApplicationExecutionState.Terminated)
                {
                    //TODO: Load state from previously suspended application
                }
    
                // Place the frame in the current Window
                Window.Current.Content = rootFrame;
            }
    
            if (e.PrelaunchActivated == false)
            {
                if (rootFrame.Content == null)
                {
                    // When the navigation stack isn't restored navigate to the first page,
                    // configuring the new page by passing required information as a navigation
                    // parameter
                    rootFrame.Navigate(typeof(MainPage), e.Arguments);
                }

                                        break;
                               }

    Re: New process/exe from a switch?

    Process.Start is what to use, but you say it didn't work for you? Post the code that you tried so we can see where it went wrong.

    Here is the full app.xaml.cs:
