Cosa potrebbe causare un errore "impossibile caricare file o assembly" relativo a "Microsoft.WindowsAzure.Configuration"?

Question

Ho un'applicazione Azure multilivello su cui sto lavorando. Utilizza i ruoli web e di lavoro dietro un front-end MVC, oltre all'archiviazione di SQL e tabella di Azure. Ha funzionato bene per un po ', sia nell'emulatore che nel cloud.

Ho appena iniziato l'aggiunta di alcune funzionalità Service Bus ad esso, aggiungendo il pacchetto di servizio di autobus da NuGet, e ora scopro che anche se tutto compila ancora, sto ottenendo il seguente errore di runtime:

Server Error in '/' Application. 
Could not load file or assembly 'Microsoft.WindowsAzure.Configuration' or one of its dependencies. Strong name signature could not be verified. The assembly may have been tampered with, or it was delay signed but not fully signed with the correct private key. (Exception from HRESULT: 0x80131045)

Ho notato che il pacchetto ServiceBus NuGet fa riferimento a una versione più recente di Microsoft.WindowsAzure.Configuration dll (1.7.0.2) e si chiedeva se ciò potesse essere la causa. Ho provato a sovrascrivere questo e cambiando tutti i riferimenti su 1.7.0.0 o 1.7.0.2 - nessuno dei due ha aiutato. Ho anche provato a rimuovere tutti i riferimenti di Azure dalla soluzione e ad aggiungere nuovamente riferimenti installando i pacchetti NuGet e facendo riferimento all'ultimo SDK. Questo non ha aiutato neanche.

Devo aggiungere che in ogni momento la dll Microsoft.WindowsAzure.Configuration è stata nella cartella bin dell'applicazione MVC e ha sempre impostato CopyLocal su true.

Ho notato che il pacchetto NuGet di Azure Configuration è stato aggiornato di recente (venerdì 27 luglio) e mi chiedo se questo potrebbe avere qualcosa a che fare con esso.

Qualcuno sa quale potrebbe essere il problema?

EDIT

solo per confermare che la rimozione del pacchetto di bus NuGet servizio risolve il problema. Il suo ripristino fa sì che il problema si ripresenti. Non so se questo è importante ma la DLL Microsoft.WindowsAzure.Configuration aggiunta come parte del pacchetto NuGet sembra avere un numero di versione incoerente. Mentre il percorso suggerisce la versione dovrebbe essere 1.7.0.2:

D: \ Work \ CLIENTS \ PageEngine \ Solutions \ PageEngine \ packages \ Microsoft.WindowsAzure.ConfigurationManager. 1.7.0.2 \ lib \ net35 pieno \ Microsoft.WindowsAzure.Configuration.dll

... il numero di versione nel proprietà ispettore è ancora 1.7.0.0

Answer 1

Questo era un problema con il complesso Microsoft.WindowsAzure.Configuration, versione 1.7.0.2

temporaneamente fissato rotolando indietro a uno 1.7.0.1 o 1.7.0.0 e poi definitivamente fissata 1.7.0.3

Answer 2

Ha avuto lo stesso problema. Ho ripristinato Microsoft.WindowsAzure.ConfigurationManager di nuovo in NuGet versione 1.7.0.1. Ora funziona OK.
