When trying to create a new Migration in Visual Studio 2019 add-migration SomeMigrationName

this throws an error. "add-migration : The term 'add-migration' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again."
