Impossible de charger le fichier ou l'assembly 'System.Web.Mvc' ou l'une de ses dépendances

Question

J'ai cette nouvelle application MVC que j'ai installée sur Windows 2008 Server. Et obtenez le message suivant lorsque j'exécute localhost.

J'ai vérifié dans le dossier Bin, et peut confirmer que le Systems.Web.MVC est là. Et la version du fichier est, 2.0.50217.0

Et dans le web.config que je l'ai défini cette assemblée,

que peut aider? Voir le message d'erreur ci-dessous:

Answer 1

Impossible de charger le fichier ou l'assembly « System.Web.Mvc, version = 3.0.0.0, ... »

votre application utilise MVC3, mais selon votre propre commentaire, le serveur a MVC2 (2.0. 501217.0)

Answer 2

J'ai eu ce problème lors du déploiement sur un serveur qui a exécuté MVC2, les fichiers qui devront être inclus dans la construction sont:

Microsoft.Web.Infrastructure.dll 
System.Web.Helpers.dll 
System.Web.Mvc.dll 
System.Web.Razor.dll 
System.Web.WebPages.Deployment.dll 
System.Web.WebPages.dll 
System.Web.WebPages.Razor.dll 

Phil Haack a fait un bon poste ici (pour savoir comment résoudre si vous rencontrez ce problème lors du déploiement)

Answer 3

Si vous avez le droit de le faire, vous pouvez download et installer MVC3 sur votre serveur web.

Answer 4

Faites un clic droit sur System.Web.Mvc dans votre dossier de référence et assurez-vous que copy local est défini sur true. Cela devrait ajouter System.web.mvc à votre dossier bin et il devrait corriger le problème.

Answer 5

Clic droit au projet -> Gérer les paquets NuGet pour solution à mettre à jour

Microsoft.AspNet.Mvc et Microsoft.Net.Compilers
