    Umbraco 4.7.1.1 and MVC 4

    Razor

    For reasons too many to mention I cannot currently upgrade our corporate site past 4.7.1.1. I have gotten everything else in the site to work with MVC 4 using assembly redirects etc. However, our Contour forms won't render due to the following error:

    Expression of type 'System.Web.Mvc.MvcWebRazorHostFactory' cannot be used for return type 'System.Web.WebPages.Razor.WebRazorHostFactory

    Is there any way I can get around this?

    Cheers,

    Ed Bishop

    Got a stack trace for the error? That way I can see where it's coming from

    Ed, did you resolve this?

    I have this in a 4.11.10 install with Contour 3.0.6.

    Tim, to upgrade to 3.0.20 can we install over the top as there doesn't seem to be an update zip for v4 installs only v6?

    Thanks, Simon

    I solved this in Umbraco v4.11 by adding some dependent assemblies.
