Oracle.ManagedDataAccess.EntityFramework - ORA-01918: пользователя 'dbo' не существует

Я пытаюсь реализовать код First Migrations с поставщиком Oracle.ManagedDataAccess 6.121.1.0, но не добился успеха вообще.

Когда я получаю ORA-код, я предполагаю, что соединение было успешно открыто. Но Миграции терпят неудачу, потому что, возможно, поставщик ведет себя как SQL Server, а не Oracle. Я думаю, что, поскольку он пытается использовать "dbo" в качестве схемы по умолчанию.

Вот мои настройки web.config:

<configuration>

             type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection, EntityFramework, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"
