Quelle surprise. Microsoft is beginning to sunset the Mac Visual Studio which never actually properly worked for many .net workflows and whose documentation was impressively MORE out of sync with itself than the rest of MSDN. I never actually figured out the voodoo of getting it to behave for .net Core web project deployment... sigh.
