Answer 1

The term 'add-migration' is not recognized as the name of a cmdlet

To solve this error, you need to install this package Microsoft.EntityFrameworkCore.Tools

1. Open your Cmd and go to the path of the project folder, then run this command

    dotnet add package Microsoft.EntityFrameworkCore.Tools
   

2. And then go to Visual Studio - Package Manager Console and run this command again
