title: Package tab missing from project properties
body: <p>Attempting to create nuget package to upload to our own nuget sever, and would like to eliminate the manual process of creating and editing the nugspec file. Everything I've read, says the setting can be pulled from the project file (if using package reference). And that the settings exist on the Package tab of the project properties window. But that tab is not there.</p>
  <p>Using vs 2019, .NetFramework 4.7.2, project is a library, and has been migrated to package reference.
  I took an existing project, right clicked the references, and used the migrate option. Package tab is non-existent</p>
  <p>I also set the nuget package manager to default to packageReference, and create a new class library.
  Package tab also non-existent</p>
  <p>The required package (when using non-SDK Style with package reference) nuget.build.tasks.pack has bee added to the references of both projects mentions</p>
  <p>Any help would be appreciated</p>
