Invece di utilizzare il provider di autenticazione incorporato di Facebook ho creato il mio CustomFacebookAuthProvider. Il motivo è che la versione integrata ha bisogno di un browser per reindirizzare l'utente a Facebook per l'autenticazione e non ne ho avuto bisogno. Ho già un token di accesso.
Così basato sulla versione ufficiale FacebookAuthProvider.cs ho creato il mio.

}
}
}
Spero che abbia senso.
