Hey there! Since the old UWP export is deprecated, I was wondering if there would be a new UWP export which might run on the new Microsoft Edge WebView2 control. This would offer numerous benefits over the old one (such as WebRTC support and WebGL). This would likely use plugin(s) for Construct that would integrate ACEs related to the Microsoft Store, Xbox Live, and other relevant SDKs.
Ah. I was under the impression that WebView2 could be packaged into a usable UWP app using WinUI3. Nonetheless, using a PWA for UWP is bulky, and creates serious limitations on what can be done, considering you have no access Xbox Live features or IAPs. Xbox One and Series denies and games that don't integrate Xbox live.
The current Windows WebView2 exporter uses a Win32 based app, and I'm not sure that's an appropriate technology for integrating with UWP/Xbox related features. It's possible to submit HTML5 exports to the Microsoft Store though - take a look at pwabuilder.com.
