I am trying EntityFrameworkCore in Visual Studio Code and I want to run "Update-Database" and "Add-Migration' commands, but there is no Package Manager Console in VSCode. what to do?
Visual Studio Code doesn't support the running of Package Manager Console commands. That integration is only available in the Visual Studio. You will have to use the Command Line Interface (CLI) instead:
