Who is this for?

This learning path is for developers who want to learn how to create cross-platform applications and leverage performance improvements on Arm64.

What will you learn?

After completing this Learning Path, you'll be able to perform the following tasks:

  • Create and build an Xamarin Forms application
  • Measure code execution performance uplift on Arm64
  • Learn how to use the Model-View-ViewModel (MVVM) architectural pattern

Prerequisites

Before starting, you'll need the following prerequisites:

  • A Windows on Arm computer such as the Lenovo Thinkpad X13s running Windows 11 or a a Windows on Arm virtual machine .
  • Visual Studio 2022 with .NET desktop development and Universal Windows Platform development installed.

You’ll create a Xamarin Forms application on Windows on Arm using the Model-View-ViewModel (MVVM) pattern. First, you’ll add a model for XY data, organize the project in Visual Studio, and connect the view model to the main page. Then, you’ll build and run the app, and time a chosen code path to measure execution on Arm64.

Where do I add the DataPoint2d model class?
Add it to the Arm64.MobileApp.XamarinForms project. Create a Models folder and then add a new C# class named DataPoint2d.cs inside that folder.
How do I connect the view model to the main page?
In MainPage.xaml, add the view-model namespace and set ContentPage.BindingContext to the appropriate view-model class. This makes the view model available to the main page.
How do I build and run the Xamarin Forms app on Windows on Arm?
Use Visual Studio to build the solution, then start debugging to launch the app. A successful build completes without errors and opens the app on Windows.
What should I check if I don't see the option to add a new class or folder?
Select the project node (not the solution or a solution folder) in Solution Explorer. If options are still missing, make sure the project is loaded and not unavailable.
How can I capture simple execution-time measurements to observe Arm64 uplift?
Instrument the relevant code path to record elapsed time, then run the app on the Windows on Arm system and note the results. Keep inputs and build configuration the same across runs to make comparisons meaningful.
