I recently began developing an app for Xbox Series X/S. The only framework that will work is UWP. When you look at the UWP docs, this is at the top of the page highlighted "If you are starting to develop Windows apps, we recommend you consider using the Windows App SDK, and WinUI rather than UWP. Although still supported, UWP is not under active development. Please see Start developing Windows apps for more information."

So no, React is a (poor) solution, not the problem. The problem is Windows can't nail down a solid SDK for it's platforms.

This metaphor is so stupidly bad it's hard to believe you guys even know what React is.
