Adım burada bulunabilir: http://www.asp.net/whitepapers/mvc4-release-notes#_Toc303253806

Özellikle sizin web.config yönlendirmeleri bağlayıcı ilgileniyoruz.

<dependentAssembly> 
    <assemblyIdentity name="System.Web.WebPages" 
     publicKeyToken="31bf3856ad364e35" /> 
    <bindingRedirect oldVersion="1.0.0.0" newVersion="2.0.0.0"/> 
    </dependentAssembly> 

ve aşağıdakileri ekleyin unutmayın sizin <appSettings>

<add key="webpages:Version" value="2.0.0.0" />
