Cross platform GUI for Powershell

Hello everyone, I’m long time lurker here.

Since Powershell 6 is now cross-platform, what GUI framework I can use to create Powershell-based GUI app which will work for Windows, MAC and eventually linux?

There ain’t one yet :). Not in PowerShell at least.

That’s a good question. Is there a gui in osx at all? I think it uses .net standard now?
