This module requires PowerShell Core

That's really weird behavior and an error message that does not point to the real problem. The module installs and imports on WS2012R2 with WMF 5.1 and on WS2019. It was only WS2016 that was failing. Maybe some of the documentation needs to point to this requirement.

@dloder0 just a reminder this is in an experimental preview state, the error messages and compatibility will be firmed up down the road.

Further, I don't think it will be a hard requirement for PS Core, 5.1 compatibility just hasn't been addressed yet but I've already got a couple issues out there that make it work once the team fixes them.
