This project allows developers to rapidly build native UX components using a React/web skillset. Developers who prefer C# and XAML can continue to use Xamarin & Xamarin.Forms for a similar high-performance implementation. Developers can only build and deploy React Native Windows apps on Windows 10 Pro and Enterprise. Also, developers cannot run the emulators and other developer tooling on Windows 10 Starter or Home editions.
