Fiducia parziale in WPF 4

Question

Ho avviato un nuovo progetto in WPF 4 (.NET 4) e provando a vedere se riesco a eseguirlo in modalità xbap. Ho bisogno di eseguire l'applicazione in piena fiducia con la nuova modalità resa disponibile in .NET 4 che chiede all'utente finale se l'applicazione di piena fiducia dovrebbe essere eseguita.

Ho impostato " Sicurezza " modalità a " Full Trust " applicazione, e si costruisce bene. Quando lo eseguo, viene generata un'eccezione e il messaggio di errore IE mostra il seguente errore.

Qualche modo per aggirarlo ??

The type of the first permission that failed was:
System.Security.Permissions.FileIOPermission

Answer 1

L'unico modo per trovare l'applicazione xbap autofirmata con piena fiducia è quello di aggiungere il certificato alla macchina del cliente (che potrebbe non essere possibile la maggior parte delle volte) o aggiungere l'URL del sito all'elenco di fiducia siti. Ho trovato quest'ultimo il più conveniente e l'applicazione funziona come se firmata da un certificato certificato rilasciato da un'autorità di fiducia.

Nota che questo è possibile solo in .NET 4.0 e non funzionerà con le versioni precedenti di WPF / .NET
