Microsoft.EntityFrameworkCore.Tools should go in the dependencies section, not tools. (Confusing, I know.)

👍1

P.S. It looks like the EF6 command is trying to execute, but having Microsoft.EntityFrameworkCore.Tools installed correctly will warn you about this and tell you how to use the right command.

What does gmo | ft Name, Path show? Does closing and re-opening the solution help?

Year, sorry. Previous error persisted during restart of studio and I didn`t cheked that after removing Microsoft.EntityFrameworkCore.Tools

After restart I see
PM> add-migration itemguid2 鈥揤erbose
Both Entity Framework Core and Entity Framework 6 are installed. The Entity Framework Core tools are running. Use 'EntityFramework\Add-Migration' for Entity Framework 6.
Build started...
Build succeeded.

Writing model snapshot to 'C:\Users\dima\Source\Reposrpano\src\pano\Migrations\ApplicationDbContextModelSnapshot.cs'.
To undo this action, use Remove-Migration.

but I cannot see any EntityFramework reference in project.json. all EntityFrameworkCore
