This may not be quite the direct answer you expect, but yes there are multiple ways to create cross-platform UIs with F#: 1. Xamarin[0]. It supports F# for everything aside from UWP targets. 2. WinForms on Mono[1]. 3. FABLE[2] to compile your F# into JavaScript. It's a very good tool and it produces really nice JavaScript as well. From there, you can run the code on the web, Electron, or React Native[3].
