Mam 2 strony internetowe, jedna jest podkatalogiem innej, ale jest aplikacją ex / root / / root / Services

Oboje używają Entity Framework 6.x, ale rodzi się strona internetowaInicjator typu dla System.Data.Entity.Internal.AppConfig 'zgłosił wyjątek ponieważ wydaje się, że widzi wiele wpisów dla tego samego dostawcy bazy danych EF z powodu zagnieżdżonego pliku web.config

Czy istnieje sposób na usunięcie kolekcji dostawców, aby nie uzyskać tego błędu? Próbowałem wprowadzić, co nie miało żadnego skutku.

Jeśli komentuję sekcję dostawców, działa

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

Ale nie chcę tego robić, ponieważ nie każde środowisko będzie miało zagnieżdżone strony internetowe. i NuGet ma tendencję do umieszczania go z powrotem. Czy mogę to dostosować programowo?

Oto pełny wyjątek i ślad stosu
