  • Microsoft just launched a new WinUI website.
  • The website breaks down the advantages of WinUI, including better performance and future-proofing applications.
  • An alpha version of WinUI 3.0 became available late last year.

Microsoft launched a new WinUI website recently. The website explains the benefits of developing apps with WinUI, including native performance and future-proofing applications. Microsoft recently expanded the reach of WinUI by releasing WinUI 3.0 in alpha form. WinUI 3.0 gives developers access to native WinUI controls in Win32 apps. Rafeal Rivera first spotted the new WinUI website.

The new website states that "WinUI makes it easy to build modern, seamless UIs that feel natural to use on every Windows device." Microsoft's vision is to have all apps on Windows utilize WinUI. The site also states that WinUI "Embodies Fluent Design to enable intuitive, accessible, and powerful experiences and the latest user interface patterns."

A main benefit of WinUI is that it's powered by an optimized C++ core. Because of this, apps using WinUI have better performance and are easier on the battery life of devices.

Two sections of the site highlight that building apps with WinUI will future-proof them for both future versions of Windows 10 and Windows 10X. The site reads, "WinUI offers a state-of-the-art UI framework for all Windows apps across both Win32 and UWP."

Towards the bottom of the site, it points out that you can use "partner platforms," such as Uno Platform, to write apps in a variety of languages. These apps will "run as-good-as-native on Windows, other operating systems, and the web," according to the site.

The information on the new WinUI website is not new, but it brings it all together into one convenient place.

  • Don't know if it has been previously announced or not, but this site also states that Windows 10 is now on 1 billion devices. Only 2 years late!
  • It was about 850 million devices two years ago. So getting to a billion devices should not be that impossible considering that many organisations are migrating to Windows 10 from Windows 7. So this site is very correct.
