InvalidcastException viene lanciato dopo aver installato ASP.NET MVC 4 beta

Question

Ricevo la seguente eccezione dopo aver installato ASP.NET MVC 4 Beta su una macchina con ASP.NET MVC 3.

System.InvalidcastException non è stato gestito dal codice utente Message = [A] System.Web.WebPages.razor.Configuration.Sostsection non può essere lanciato su [b] System.Web.WebPages.razor.configuration.hostsection. Tipo A proviene da 'System.Web.WebPages.razor, versione = 1.0.0.0, Culture = Neutral, PublicKeyToken = 31bf3856ad364e35' nel contesto 'predefinito' in posizione 'C: Windows Microsoft.net Assembly Gac_msil System .Web.webpages.razor v4.0_1.0.0.0__31bf3856ad364e35 System.web.webpages.razor.dll '. Il tipo B ha origine da 'System.Web.WebPages.razor, versione = 2.0.0.0, Culture = Neutral, PublicKeyToken = 31bf3856ad364e35' nel contesto 'predefinito' in posizione 'C: Windows Microsoft.NET ASSEBBLICE GAC_MSIL System .Web.webpages.razor v4.0_2.0.0.0__31bf3856ad364e35 system.web.webpages.razor.dll '. Source = System.Web.WebPages.razor

Questo mi blocca completamente e mentre vorrei mantenere la beta, potrei aver bisogno di rimuoverla completamente per sbarazzarmi dell'eccezione.
