Tutorial: Expand the Reach of your Existing C# WinUI 3 App

To get started, you’ll need Visual Studio 2022 version 17.4 or later, along with the necessary tools and workloads for Windows App SDK, web development, iOS/Android development, and desktop development. Once your environment is set up, you’ll install the Uno Platform solution templates and create a new Uno Platform application.

The tutorial provides step-by-step instructions for creating a multi-platform application using Uno Platform. It explains how to copy the code from your existing WinUI 3 project into the multi-platform project, enabling code reuse. You’ll also learn how to add image assets to the project and prepare your app for the multi-platform experience.

Uno Platform’s XAML flavor ensures that the view works seamlessly across all supported platforms. By copying the contents of your existing Window element into the Page element of the Uno Platform project, you can achieve platform consistency with minimal effort.

Overall, this tutorial empowers you to target multiple platforms with your existing WinUI 3 app, expanding your app’s reach and user base. With the Uno Platform, you can leverage your existing codebase and create a consistent user experience across mobile, web, and desktop platforms. So why limit your app to a single platform when you can easily extend it to a broader audience?
