Impossibile caricare il file o l'assembly 'System.Management.Automation'

Question

Ho scritto un'applicazione web asp.net MVC 3 ('ADReporter') sul mio computer locale che utilizza Powershell per recuperare alcuni dati. Se eseguo questa applicazione localmente, tutto funziona correttamente. Ora sto cercando di farlo funzionare sul mio server di Windows 2008, ma quando sto cercando di accedervi, ottengo seguente stack trace:

Server Error in '/ADReporter' Application. 

Could not load file or assembly 'System.Management.Automation' 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) 

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

può piacere a qualcuno mi aiuti? Ho cercato questo errore per giorni ... Grazie in anticipo!

Answer 1

Il problema era che non installavo correttamente Windows Management Framework 3.0 sul server.
