It's because you haven't selected the Authentication Type as 'Individual Users' from drop-down menu on 'Additional Information Page' after creating project.
I'll explain through screenshots.
When you select None Like this: Authentication Type: None . You'll be missing the NuGet packages and Data folder with DbContext and settings for the database in appsettings.json. Like this: No Npm packages
And When you'll select 'Individual Users' Authentication Type: Individual Users It'll be with pre installed NuGet packages and Data folder with DbContext and settings for the database in appsettings.json. Looking like this Pre installed packages
I hope this helps and solves your problem :)
CommunityorDeveloper package? Furthermore, please double check the type of project you have created are same.
