Konnte Datei oder Assembly 'System.Web.Mvc' oder eines seiner Abhängigkeiten nicht laden

Question

Ich habe diese neue MVC-Anwendung, die ich auf Windows 2008 Server installiert habe. Und bekomme die folgende Nachricht, wenn ich den localhost ausführe.

Ich habe in den Ordner Bin eingecheckt und kann bestätigen, dass der Systems.Web.MVC da ist. Und die Version der Datei ist, 2.0.50217.0

und in der web.config ich diese Baugruppe definiert haben,

Kann jemand helfen? Siehe die Fehlermeldung unter:

Ihre Anwendung verwendet MVC3 laden, aber Sie Ihren eigenen Kommentar nach dem Server hat MVC2 (2.0. 50217.0)

Answer 2

Ich hatte dieses Problem bei der Bereitstellung auf einem Server, der MVC2 ausgeführt hat, die Dateien, die im Build enthalten sein müssen:

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 hat einen guten Beitrag hier getan (für wie zu lösen, wenn Sie in dieses Problem bei der Bereitstellung)

Answer 3

Wenn Sie Rechte haben, dies zu tun, können Sie download und installieren MVC3 auf Ihrem Webserver.

Answer 4

Klicken Sie mit der rechten Maustaste auf System.Web.Mvc in Ihrem Referenzordner und stellen Sie sicher, dass copy local auf true gesetzt ist. Das sollte System.web.mvc zu Ihrem bin-Ordner hinzufügen und es sollte das Problem beheben.
