J'ai fait cette terrible erreur de mise à niveau de MVC4 vers MVC5 en pré-version en mettant à jour le rasoir et la page Web mvc dans mes références, j'ai System.Web.Mvc
, System.Web.Webpages
, System.Web.Webpages.Razor
et System.Web.Razor
comme version v4.0.30319, lorsque j'exécute mon application, j'obtiens
[A]System.Web.WebPages.Razor.Configuration.HostSection cannot be cast to
[B]System.Web.WebPages.Razor.Configuration.HostSection.
Type A originates from
'System.Web.WebPages.Razor, Version=2.0.0.0, Culture=neutral,
PublicKeyToken=31bf3856ad364e35' in the context 'Default' at location
'C:\Windows\Microsoft.Net\Assembly\GAC_MSIL\System.Web.WebPages.Razor\v4.0_2.0.0.0__31bf3856ad364e35\System.Web.WebPages.Razor.dll'.
Type B originates from
'System.Web.WebPages.Razor, Version=3.0.0.0, Culture=neutral,
PublicKeyToken=31bf3856ad364e35' in the context 'Default' at location
'C:\Windows\Microsoft.NET\Framework64\v4.0.30319\Temporary ASP.NET Files\membership\c70f06fe\9163b1ca\Assembly\dl3\291c956e\73c25daa_cf74ce01\System.Web.WebPages.Razor.dll'.
est-ce la même chose que http://www.asp.net/whitepapers/mvc4-release-notes
Merci
Ajout d'une trace de pile:

A découvert ce qui doit être fait dans Views\Web.config

Et c'était tout. Travail accompli! :RÉ
je suggère de voir cela depuis http://asp.net site web
venez-vous de mettre à jour les références du projet? Avez-vous également vérifié le web.config? Il existe également ces bibliothèques référencées et généralement avec des numéros de version spécifiques de la bibliothèque elle-même.
dans le web.config vous pouvez trouver les bibliothèques référencées par exemple dans:
<runtime>
<assemblyBinding xmlns="urn:schemas-Microsoft-com:asm.v1">
<dependentAssembly>
<assemblyIdentity name="System.Web.Helpers" publicKeyToken="31bf3856ad364e35" />
<bindingRedirect oldVersion="0.0.0.0-2.0.0.0" newVersion="2.0.0.0" />

C'est à peu près un ensemble et oubliez-le, donc j'espère que cela peut aider avec les mises à niveau de MVC4 à MVC5. Assurez-vous ensuite de vérifier/référencer vos versions de références de projet. Je suis passé à utiliser simplement NuGet pour la gestion des packages et la gestion des dépendances.
