There is nothing preventing these GUI frameworks from working on .NET Core. They might need some work to support it but its entirely possible.

What Hacker News says
13 sourcesIt looks like there's two options for cross-platform XAML UIs:
* Prism [1], which doesn't seem to support .NET Core. It was originally created by Microsoft Patterns & Practices, but then open sourced it. It's now community maintained. It looks like it's still being actively developed as there was a merge 4 days ago.
* Avalonia [2], which supports .NET Core but is still in alpha.

In Electron.Net: Build cross platform desktop apps using .NET core and ASP.NET corethose guys are making progress
https://github.com/AvaloniaUI/Avalonia
Though I wish they didn't choose xaml/wpf way which is pretty much over engineered imho. React like api would be awesome.
In Electron.Net: Build cross platform desktop apps using .NET core and ASP.NET coreI assume there's plenty of options... Qt or gtk bindings, electron, etc
Looks like Xamarin is building full cross-platform support via XAML
https://blog.xamarin.com/glimpse-future-xamarin-forms-3-0/
Avalonia seems like a straightforward reimplementation of WPF that is already usable.

DotVVM is working on electron support, and I work with it already. I like it.

In KeePass 2.37 has been releasedThere's a few projects working in this direction, one of the coolest being Avalonia (IMO, at least). It's still in "alpha", although I heard a beta was not far off.

In Introducing .NET IL LinkerThe technology will work with any kind of app. I know that some folks working on one of the bigger UI frameworks, Avalonia (https://github.com/AvaloniaUI/Avalonia) have toyed with it recently. One thing to keep in mind is that lots of these frameworks do dynamic, reflection-based data binding, which might be easily broken if the linker removes too much stuff. You can tinker with the settings of the linker to force it to preserve things that are actually necessary.
In Introducing .NET IL LinkerXamarin makes this separation work pretty well. Not Xamarin.Forms but a core business logic project with custom UI projects for each platform.
I'm hoping this will turn into a good solution. Xamarin already supports Mac (in addition to iOS and Android) and when it aligns more with UWP (XAML Standard etc.) that could cover a large slice of the platforms you'd want to target.
React native could be another option. I hear Android support has gotten better and you can supposedly also target UWP: https://github.com/Microsoft/react-native-windows
I wrote this a while ago but it's still fairly relevant: https://unop.uk/cross-platform-native-mobile-app-development...
You could also look at https://github.com/AvaloniaUI/Avalonia or https://github.com/picoe/Eto.
In Announcing .NET Core 2.0It doesn't necessarily have to be multiple UIs (although that's probably better in the long term) but there are x-platform options like:
1) Eto.Forms (https://github.com/picoe/Eto)
2) Avalonia (https://github.com/AvaloniaUI/Avalonia)
In KeePassXC 2.2.0 released with YubiKey and TOTP supportApparently this is a hot topic.
The options I'm aware of are:
https://github.com/picoe/Eto (OP - BSD)
https://github.com/AvaloniaUI/Avalonia (MIT)
Currently only with a preview for Mac, Xamarin.Forms is roadmapped for desktop platforms "Q3 2017": https://blog.xamarin.com/glimpse-future-xamarin-forms-3-0/
Licensing for Xamarin Forms was funky for a while (required paying for Xamarin prior to MS acquisition) but appears to be MIT now.
In Show HN: Cross Platform .NET Desktop Application FrameworkI don't spend much time w/ that stack, but Avalonia [1] seems to be a big player. Even better, they recently merged .Net core support [2]. You of course lose some native look and feel.

In Cross platform GUIs and Nim macrosAvaloniaUI looks like a good choice. The demos shown in the README are impressive[1].
