EF7 RC1 термин 'Scaffold-DbContext' не распознается

Я пытаюсь использовать EF7 RC1 для построения каркаса из существующей базы данных, следуя инструкциям на странице
https://media.readthedocs.org/pdf/ef/latest/ef.pdf

Когда я выполняю команду из консоли диспетчера пакетов

Scaffold-DbContext -provider EntityFramework.MicrosoftSqlServer -connection "Server=(localdb)MSSQLLocalDB;Initial Catalog=Clients_Local;Integrated Security=True;Connect Timeout=30;Encrypt=False;TrustServerCertificate=False;ApplicationIntent=ReadWrite;MultiSubnetFailover=False"

Я получаю эту ошибку

Scaffold-DbContext : The term 'Scaffold-DbContext' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again.

At line:1 char:1

+ Scaffold-DbContext -provider EntityFramework.MicrosoftSqlServer -conn ...

+ ~~~~~~~~~~~~~~~~~~

+ CategoryInfo          : ObjectNotFound: (Scaffold-DbContext:String) [], CommandNotFoundException

+ FullyQualifiedErrorId : CommandNotFoundException

Мой проект.json выглядит так

После изучения этого вопроса я удалил содержимое C:Users.dnxbin и обновленный dnvm с помощью

https://github.com/aspnet/Home#cmd

Но я все еще получаю ту же ошибку.
