2020 UPDATE

I personally prefer to use dotnetcommand wherever it is possible.

The solution I found working out fine is changing the default project reference in the main project as below

  
    
      true
      {ProjectName}.dll
    
   

This solution is confirmed that it works when targeting netstandard2.0and above.
