It 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.
