@Calinou @aaronfranke Well that drives me nuts… It worked! You MUST use .NET Core 3.1 SDK not .NET 5!

from my azure yaml

- task: UseDotNet@2
  displayName: 'Use .NET Core sdk 3.1'
  inputs:
    packageType: 'sdk'
    version: '3.x'
    includePreviewVersions: false

@aaronfranke Understandable, I have updated to the 3.2.4.rc3 and that has fixed all my immediate issues. I will try to contribute in a helpful manner as I proceed. Thank you all for the great work!

I reverted back to the stable repository. Looks like additionally installing mono-roslyn fixes it.
