using System;
using System.Threading.Tasks;
using Windows.UI;
using Windows.UI.Xaml;
using Windows.UI.Xaml.Controls;
using Windows.UI.Xaml.Input;
using Windows.UI.Xaml.Media;

public class Library
    private const int win = 1;
    private const int draw = 0;
    private const int lose = -1;

    private int[,] match = new int[3, 3]
        { draw, lose, win },
        { win, draw, lose },
        { lose, win, draw }

    private int[] values = new int[] { 0, 1, 2 };
    private string[] options = new string[] { "\uED5B", "\uE130", "\uE16B" };

    private Random random = new Random((int)DateTime.Now.Ticks);

    private async Task<ContentDialogResult> ShowDialogAsync(string title, int option)
        ContentDialog dialog = new ContentDialog()
            Title = title,
            Content = GetShape(option, false),
            PrimaryButtonText = "OK"
        return await dialog.ShowAsync();

    private async void Choose(int option)
        int player = values[option];
        int computer = random.Next(0, 2);
        int result = match[player, computer];
        string message = string.Empty;
            case win:
                message = "You Win!";
            case lose:
                message = "You Lost";
            case draw:
                message = "You Draw";
        await ShowDialogAsync($"Computer Picked - {message}", computer);

    private Grid GetShape(int option, bool useEvent)
        Grid grid = new Grid()
            Tag = option,
            Margin = new Thickness(5),
            Height = 80,
            Width = 80,
            Background = new SolidColorBrush(Colors.Black),
        TextBlock text = new TextBlock()
            Text = options[option],
            FontSize = 66,
            FontFamily = new FontFamily("Segoe MDL2 Assets"),
            Foreground = new SolidColorBrush(Colors.White),
            VerticalAlignment = VerticalAlignment.Center,
            HorizontalAlignment = HorizontalAlignment.Center
        if (useEvent)
            grid.Tapped += (object sender, TappedRoutedEventArgs e) =>
                Grid selected = (Grid)sender;
                int tag = (int)selected.Tag;
        return grid;

    private void Layout(ref Grid grid)
        StackPanel panel = new StackPanel()
            Orientation = Orientation.Horizontal,
            HorizontalAlignment = HorizontalAlignment.Center
        for(int i = 0; i < 3; i++)
            panel.Children.Add(GetShape(i, true));

    public void New(ref Grid grid)
        Layout(ref grid);

Step 8

Then in the Solution Explorer select MainPage.xaml

From the Menu choose View and then Designer


Step 10

The Design View will be displayed along with the XAML View and in this between the Grid and /Grid elements, enter the following XAML:

It should appear as such:


Step 11

From the Menu choose View and then Code


Step 12

Once in the Code View, below the public MainPage() { … } the following Code should be entered:

Library library = new Library();

private void New_Click(object sender, RoutedEventArgs e)
	library.New(ref Display);

It should then appear as such:


Step 13

That completes the Universal Windows Application so Save the Project then in Visual Studio select the Local Machine to run the Application
