I tried it, and it's not ready for production. Publishing is half-finished and it appears to be a bit of dumb luck whether an app runs properly if at all.

Just wrap a blazor web app in electron/capacitor. It's compatible with older devices while running faster, being smaller, and doesn't depend on a bleeding edge webview present on the device. (which is why some android devices from even just 3 years ago won't run the maui/blazor app)

I see the appeal of these cross platform solutions but what nobody mentioned is 1000 paper cuts along the way. Scratch that, make them a million. IMO it's better to create a native app and host shared content in a (WK)webview, similar to mentioned approach, but keep native stuff native.

Microsoft should stop marketing stuff before it's ready. Who do they think they are? Ubisoft?
