Since MS is no stranger to regularly building new frameworks, they should build one that is natively supported in Windows, with no compromises relative to other APIs like WPF or Win32, while also supporting macOS, iOS and Android as targets. Some functionality that's not supported in iOS, say, like full multitasking, should degrade gracefully. Think of it as a hybrid app framework that also is the first-party framework on one OS. No one has done that so far, and it would be interesting to see someone try. That will give developers a solid incentive to use this API, unlike others like WPF, Silverlight, WinRT, etc. The benefit for MS will be that Windows gets the best possible experience, rather than a least-common denominator one, as with Electron.
