VS 2017 .Net Core 2.0 Console Application Publish Fail

the .NET Core 2.0 or later versions, minimum version is osx.10.12-x64

From what I understand, that OSX-version should be too old to support ( /be supported by?) .NET Core 2.0.

What I don't understand though, is why it would work (a) when run from a command line, and (b) in newer / other versions of Visual Studio.
