What you need to know

  • Microsoft has this week released Project Reunion 0.5.
  • It includes a new version of WinUI 3 that works with Uno Platform, which has also been updated.
  • Together, these will allow developers to reuse their code for other platforms including iOS and macOS.

Windows 10 developers can reuse their WinUI 3 code to bring their apps to other platforms including iOS and macOS.

It comes with the release of Project Reunion 0.5 from Microsoft and Uno Platform 3.6, as reported by our friends at Windows Central:

Microsoft announced the rollout of Project Reunion 0.5 earlier today. It's a major milestone in terms of Windows 10 development, in part because it is the first complete release of Project Reunion that includes WinUI 3. On the heels of that announcement, Uno Platform announced the release of Uno Platform 3.6. This updated version of Uno Platform allows developers to reuse their code from WinUI 3 applications on other platforms, including iOS, Android, macOS, the web, and Linux.

Thanks to Project Reunion 0.5 and Uno Platform 3.6, developers can now create apps for Windows 10 before sharing them for other platforms. The new version of Uno Platform also brings updates:

In addition to support for WinUI 3, Uno Platform released additional controls for enabling end-user interactions with date and file input controls and a new Cupertino theme in the Uno Platform Gallery. Uno Platform already provided Fluent and Material themes before the update to version 3.6.

Francois Tanguay, CEO of Uno Platform stated "We are delighted to see WinUI 3 launch as part of Project Reunion and alongside WinUI. We are very proud to work closely with Microsoft to ensure Uno Platform can provide day-zero support for WinUI 3 and bring WinUI-built applications everywhere, including Web, Linux, macOS, iOS and Android."

Microsoft's Partner Group program manager Mike Harsh said:

With WinUI 3 – Project reunion 0.5 we are making investments to enable developers to improve Windows experiences. We are pleased to see open source projects like Uno Platform take that mission further by extending the reach of WinUI to Web, Linux, macOS, iOS and Android.

The move gives Windows developers more flexibility to create apps and then release them on other major platforms including macOS and iOS.
