Hi Stephen,
The question was already addressed on the X# forums and although all the interfaces are not ready yet, here is a video that Robert posted to show that X# does actually support .NET Core already for WinForms/WFP.
Robert also stated that there should not be any problem as the X# compiler/runtime does not use any non-core interfaces except if there are some they not aware of, but would quickly be implemented/fixed. Keep in mind that even c# does not yet have a "visual studio" interface to WinForms/WPF.

Or how to get M$ code running in an open source environment of your choice.
