Because of this question I tried to change my Azure Devops build process to use DotNet isntead of Nuget
The task is now
- task: DotNetCoreCLI@2
  inputs:
    command: pack
    packagesToPack: '**/SBD.*.csproj'
    versioningScheme: byPrereleaseNumber
    majorVersion: '$(Major)'
    minorVersion: '$(Minor)'
    patchVersion: '$(Patch)
And the error is
error MSB4057: The target "pack" does not exist in the project
I found this question but it is not for DevOps
The answer mentions I need to install the Nuget.Build.Tasks Pack package from Nuget
So I did that
Now the log in devops states
C:\Users\VssAdministrator\.nuget\packages\nuget.build.tasks.pack\5.6.0\build\NuGet.Build.Tasks.Pack.targets(198,5): 
error : Authors is required. [D:\a\1\s\Common.WinForms\SBD.Common.WinForms.csproj]
