CrossOver Support - Community Forums

I was wondering how feasible it would be to run Universal Windows Platform apps (UWP, Modern. Metro, whatever one wants to call them) under Wine/Crossover?

I know the ability isn't there currently (no way to call the runtime, etc). What I was curious about was how much of UWP even uses the legacy Win32 code, other than for file-system, network and display access. I expect the API might abstract the system so far it doesn't even see the old MSWin subsystems.

There shouldn't be anything from preventing Wine / Crossover developers from implementing the new UWP / WinRT APIs but it's fundementally different and the way UWP apps are created, installed and ran is totally different from normal .EXEs but Microsoft does permit .APPX UWP packages to be installed outside of the Windows store, so that opens development potential for Wine or another project to someday implement support.

That said, even though Wine doesn't support UWP now, it's still possible to use UWP apps on Linux in a Wine-like manner with some specialized Windows guest virtualization and some script software I'm working on to help integrate UWP and Cortana digital assistant into Linux.

If you're interested, you can see these recent videos I've uploaded for a better idea about what I'm talking about:
