Chiara Mooney & Shiven Mian – Building for Microsoft (Chain React 2023)

AFAIK the Start Menu itself is still C++ and XAML however only the Recommended section is build with React Native [1]. Funnily or rather sadly, they seem to be quite proud of using it as seen in the video. 1: ▶ this video

I found this: ▶ this video I googled the names of the people holding the talk and they're both employed by Microsoft as software engineers, I don't see any reason to doubt what they're presenting. Not the whole start menu is React Native, but parts are.

This has been making the rounds on Twitter and the story never dies despite being essentially false. (Backed by “I hit Start and got a CPU spike”) Just the “Recommended” section - the lower frame showing M365 files & frequent apps - is built with React Native[1]. And, AFAIK, it uses Microsoft’s React Native for Windows that renders real XAML components, so it’s not just a masquerading WebView or something. The Start Menu itself is still C++ and XAML. (And I think WinUI 2, i.e. the system-included variation of WinUI) It’s not just all a web thing or a JS-backed React Native app. 1: ▶ this video
