Order Game

Learn creating an Order Game using Windows App SDK with this Tutorial

Order Game

Order Game shows how you can create a simple game where the objective is to arrange Squares in the correct sequence in the quickest time possible using a toolkit from NuGet using the Windows App SDK.

Step 1

Follow Setup and Start on how to get Setup and Install what you need for Visual Studio 2022 and Windows App SDK.

In Windows 11 choose Start and then find or search for Visual Studio 2022 and then select it.
Visual Studio 2022
Once Visual Studio 2022 has started select Create a new project.
Create a new project
Then choose the Blank App, Packages (WinUI in Desktop) and then select Next.
Blank App, Packages (WinUI in Desktop)
After that in Configure your new project type in the Project name as OrderGame, then select a Location and then select Create to start a new Solution.
Configure project

Step 2

Then in Visual Studio within Solution Explorer for the Solution, right click on the Project shown below the Solution and then select Manage NuGet Packages...

Manage NuGet Packages

Step 3

Then in the NuGet Package Manager from the Browse tab search for Comentsys.Toolkit.WindowsAppSdk and then select Comentsys.Toolkit.WindowsAppSdk by Comentsys as indicated and select Install

NuGet Package Manager Comentsys.Toolkit.WindowsAppSdk

This will add the package for Comentsys.Toolkit.WindowsAppSdk to your Project. If you get the Preview Changes screen saying Visual Studio is about to make changes to this solution. Click OK to proceed with the changes listed below. You can read the message and then select OK to Install the package, then you can close the tab for Nuget: OrderGame by selecting the x next to it.

Step 4

Then in Visual Studio within Solution Explorer for the Solution, right click on the Project shown below the Solution and then select Add then New Item…

Add New Item

Step 5

Then in Add New Item from the C# Items list, select Code and then select Code File from the list next to this, then type in the name of Library.cs and then Click on Add.

Add New Code File

Step 6

You will now be in the View for the Code of Library.cs, within this type the following Code:

using Comentsys.Toolkit.WindowsAppSdk;
using Microsoft.UI.Xaml;
using Microsoft.UI.Xaml.Controls;
using System;
using System.Collections.Generic;
using System.Collections.ObjectModel;
using System.Linq;

public class Library
    private const string title = "Order Game";
    private const int size = 6;

    private readonly Random _random = new((int)DateTime.UtcNow.Ticks);
    private readonly ObservableCollection<int> _values = new();

    private Dialog _dialog;
    private GridView _view;
    private DateTime _start;

    private List<int> Choose(int minimum, int maximum, int total) =>
        Enumerable.Range(minimum, maximum)
            .OrderBy(r => _random.Next(minimum, maximum))

    private void Completed()
        if (_values.OrderBy(o => o).SequenceEqual(_values))
            TimeSpan duration = (DateTime.UtcNow - _start).Duration();
            _dialog.Show($"Completed in {duration:hh\\:mm\\:ss}", title);
            _view.IsEnabled = false;

    // Layout & New

The Class defined so far Library.cs has using for package of Comentsys.Assets.FluentEmoji and others. It also has Constants to represent things needed in the game and there are Variables to keep track of values used in the game along with Methods for Choose to pick the random sequence of numbers to be put in Order and Completed which will determine if the game has been finished and display a Dialog showing the time it took do to so.

Step 7

While still in the Class for Library.cs after the Comment of // Layout & New type in the following Methods:

private void Layout(Grid grid)
    _view = new()
        ItemsPanel = grid.Resources[nameof(ItemsPanelTemplate)]
            as ItemsPanelTemplate,
        ItemTemplate = grid.Resources[nameof(DataTemplate)]
            as DataTemplate,
        SelectionMode = ListViewSelectionMode.Single,
        CanReorderItems = true,
        ItemsSource = _values,
        CanDragItems = true,
        AllowDrop = true,
        IsEnabled = true,
        CanDrag = true,
    _view.DragItemsCompleted += (ListViewBase sender, 
        DragItemsCompletedEventArgs args) =>

public void New(Grid grid)
    _dialog = new Dialog(grid.XamlRoot, title);
    _start = DateTime.UtcNow;
    var values = Choose(1, size * size, size * size);
    foreach (var value in values)

Layout will create the layout for the game which comprises of an ItemsPanel which will use Templates to create the look-and-feel for the elements of the game and will check if the game is finished using Completed when the elements are reordered and New will setup and start a new game.

Step 8

Within Solution Explorer for the Solution double-click on MainWindow.xaml to see the XAML for the Main Window.
Solution Explorer MainWindow.xaml

Step 9

In the XAML for MainWindow.xaml there will be some XAML for a StackPanel, this should be Removed:

<StackPanel Orientation="Horizontal" 
HorizontalAlignment="Center" VerticalAlignment="Center">
    <Button x:Name="myButton" Click="myButton_Click">Click Me</Button>

Step 10

While still in the XAML for MainWindow.xaml below <Window>, type in the following XAML:


The XAML for <Window> should then look as follows:


Step 11

While still in the XAML for MainWindow.xaml above </Window>, type in the following XAML:

        <Grid Margin="50" Name="Display" 
        VerticalAlignment="Center" Loaded="New">
                <DataTemplate x:Name="DataTemplate">
                    <ui:Piece Value="{Binding}" IsSquare="True" 
                    Fill="Black" Foreground="White" />
                <ItemsPanelTemplate x:Name="ItemsPanelTemplate">
                    <ItemsWrapGrid Orientation="Horizontal" 
    <CommandBar VerticalAlignment="Bottom">
        <AppBarButton Icon="Page2" Label="New" Click="New"/>

This XAML contains a Grid with a Viewbox which will Scale a Grid. It has a Loaded event handler for New which is also shared by the AppBarButton and the Grid also has Resources which defines the Templates.

Step 12

Within Solution Explorer for the Solution select the arrow next to MainWindow.xaml then double-click on MainWindow.xaml.cs to see the Code for the Main Window.
Solution Explorer MainWindow.xaml.cs

Step 13

In the Code for MainWindow.xaml.cs there be a Method of myButton_Click(...) this should be Removed by removing the following:

private void myButton_Click(object sender, RoutedEventArgs e)
    myButton.Content = "Clicked";

Step 14

Once myButton_Click(...) has been removed, within the Constructor of public MainWindow() { ... } and below the line of this.InitializeComponent(); type in the following Code:

private readonly Library _library = new();

private void New(object sender, RoutedEventArgs e) =>

Here an Instance of Library is created then below this is the Method of New that will be used with Event Handler from the XAML, this Method uses Arrow Syntax with the => for an expression body which is useful when a Method only has one line.

Step 15

That completes the Windows App SDK application. In Visual Studio 2022 from the Toolbar select OrderGame (Package) to Start the application.
OrderGame (Package)

Step 16

Once running you win by putting all the numbers in Order from 1 to 36 from left to right as quickly as possible by dragging and moving them into the correct Order, or you can select New to start a new game.

Step 17

To Exit the Windows App SDK application, select the Close button from the top right of the application as that concludes this Tutorial for Windows App SDK from tutorialr.com!
