Your startup project doesn't reference Microsoft.EntityFrameworkCore.Design

Question

I have 2 projects in my solution, I have a project with Entity Framework Core installed:

And in the other ASP.NET Web API project I have these packages:

Answer 1

"Your 'project name' does not refer to your startup project Microsoft.EntityFrameworkCore.Design. This package is required for the Entity Framework Core Tools to work. Make sure your startup project is correct, install the package and try again."

If you get this error, try 'Build > Clean Solution' in your project and then try running your command again.

This worked in my project. Or you may want to look at the documentation.

I use .Net Core 3.1 version in my project.
