L'initialiseur de type pour 'Système.Les données.De l'entité.Interne.AppConfig' a déclenché une exception sur un Sous-Site web

J'ai 2 sites, l'un est un sous-répertoire d'un autre, mais est une Application
ex: /root & /root/Services

Ils utilisent tous les deux Entity Framework 6.x, mais le site web enfant est en train de jeter L'initialiseur de type pour le Système.Les données.De l'entité.Interne.AppConfig' a déclenché une exception, car il semble être de voir à plusieurs entrées pour le même EF Fournisseur de Base de données en raison de la web imbriqué.config

Est-il un moyen pour effacer les prestataires de collecte, de sorte que je n'ai pas cette erreur? J'ai essayé de les mettre dans ce qui n'a eu aucun effet.

Si j'en commentaire fournisseurs de la section, il fonctionne

<providers>
  <provider invariantName="System.Data.SqlClient" type="System.Data.Entity.SqlServer.SqlProviderServices, EntityFramework.SqlServer" />
</providers>
</entityFramework>

Mais je ne veux pas le faire parce que pas chaque environnement va avoir imbriqués les sites web. et NuGet tend remet en.
Puis-je régler ce par programmation?

Voici la pleine exception et la trace de la pile
