EF core add migrations in ASP.net core multilayered architecture

I have recently started ASP.net core project with multilayered architecture, where CatalogDbContext and StartUp class in different layers:

enter image description here

I want to add migrations to DroneStore.Data layer. I change in command prompt current directory to ../DroneStore.Data/ and add command:

dotnet ef migrations add Initial

And got an error:

Unable to create an object of type 'CatalogDbContext'. For the different patterns supported at design time, see https://go.microsoft.com/fwlink/?linkid=851728

When I change current directory to ../DroneStore.Web/ and add this command i got error:

Your target project 'DroneStore.Web' doesn't match your migrations assembly 'DroneStore.Data'. Either change your target project or change your migrations assembly

Any suggections?

1) Change your currend directory in command prompt to:

cd ../DroneStore.Data/

2) Add to command -s option with path to StartUp project folder:

dotnet ef migrations add Initial -s ../DroneStore.Web/
