InvalidCastException se arroja después de instalar ASP.NET MVC 4 beta

El tipo A se origina en 'System.web.webpages.razor, versión = 1.0.0.0, cultura = neutral, publickeyToken = 31bf3856ad364e35' en el contexto 'predeterminado' en ubicación 'c: windows microsoft.net ensamblaje gac_msil system .Web.webpages.razor v4.0_1.0.0.0__31bf3856ad364e35 system.web.webpages.razor.dll '. El tipo B se origina en 'System.web.webpages.razor, versión = 2.0.0.0, cultura = neutral, publickeyToken = 31bf3856ad364e35' en el contexto 'predeterminado' en ubicación 'c: windows microsoft.net ensamblaje gac_msil system .Web.webpages.razor v4.0_2.0.0.0__31bf3856ad364e35 system.web.webpages.razor.dll '.

Esto me bloquea por completo y, aunque me gustaría mantener la versión beta, podría necesitar eliminarla por completo para deshacerme de la excepción.
