Port your app to the Windows Runtime

[This article is for Windows 8.x and Windows Phone 8.x developers writing Windows Runtime apps. If you’re developing for Windows 10, see the latest documentation]

Do you have a Windows Phone Silverlight app, Windows Presentation Foundation (WPF) app, a Microsoft Silverlight app, Android, iOS, or web app? Bring it to the Windows Runtime where you can create a single project that targets both Windows and Windows Phone. Your app will benefit from exciting new hardware, great monetization opportunities, a modern API set, common UI controls, and a range of input modalities including mouse/keyboard, touch, and speech.

Note  This section is for Windows 8.x developers writing Windows Runtime apps. If you’re developing for Windows 10, see Porting apps to Windows 10.


The Windows Runtime (WinRT) is the technology that lets you build an app that targets both Windows and Windows Phone. This porting guide explains the differences between your current app's technology and the Windows Runtime. Once the path between technologies is understood, you'll be able to dive into the rest of the Developer Center, which is a comprehensive resource for developing Universal Windows Platform (UWP) apps. A good way to do that, when you're ready, is to start with How to develop a Store app.

Why Windows?

Whether you are porting an app, or creating a new app, supporting Windows makes good business sense—and it's fun! With modern languages, tools, and frameworks, and fresh user interface controls and experiences, your ideas will never have looked better. Use your skill set and even source code—from other XAML platforms, for example—to update your apps to the latest technologies, and explore new markets.

User interface Make the most of new XAML and WinJS controls to create rich, engaging apps. Support for Universal Windows apps means you can build for desktop, tablet and phone from one Visual Studio solution.
