What you need to know

  • Uno Platform 3.6 launched today, and it supports Project Reunion 0.5.
  • Project Reunion 0.5 supports WinUI 3 and is the first production version of Project Reunion.
  • Developers can now use Project Reunion 0.5 to make modern apps with WinUI 3 and Uno Platform to bring the code of those apps to other platforms.

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.

With the rollout of Project Reunion 0.5 and Uno Platform 3.6, developers can create modern apps on Windows 10 using the latest from WinUI 3 and then bring that over to all other major platforms.

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.

Uno Platform and Microsoft worked hand-in-hand for these releases, and it isn't a surprise that Project Reunion 0.5 and Uno Platform 3.6 came out within hours of each other. Speaking of that collaboration and the new technologies, Francois Tanguay, CEO of Uno Platform, said:

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 Partner Group program manager Mike Harsh also shared his thoughts:

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.

With support for every major platform, including the web, developers can now utilize Uno Platform to bring code from modern Windows apps built with WinUI 3 to just about every type of device that people work with.
