Uno Platform 3.6

WinUI 3 and Project Reunion Day 0 support. New controls and theme added.

We are pleased to announce the general availability of Uno Platform 3.6. The new release enables software developers to reuse the same code from their WinUI 3 built applications for Windows and take them cross-platform to Web, Linux, macOS, iOS and Android with Uno Platform.

In addition to Day-0 support for WinUI 3 and Project Reunion, Uno Platform released additional controls for enabling end-user interactions with Date and File input controls, as well as a new Cupertino theme preview in Uno Platform Gallery. Prior to 3.6 release Uno Platform already provided Fluent and Material theme out-of-box support for developers to reuse in order to speed up multi-platform application development.

Uno Platform is built on top of .NET and it also takes advantage of great Windows platform features such as accessibility, touch, keyboard inputs as well as rich controls such as Charts, Gauges and Grid coming from either Windows Community Toolkit or 3rd party vendors like Infragistics and Syncfusion. Uno Platform team believes the Windows platforms provide the most delightful end-user applications which can, by utilizing Uno Platform, be easily taken to all platforms where WinUI does not run on.

We are delighted to see WinUI 3 launch as part of Project Reunion and alongside WinUI” said Francois Tanguay, CEO of Uno Platform. “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 “.

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.” – said Microsoft Partner Group Program Manager, Mike Harsh
