Exception when rendering form in Umbraco using Contour v.3.0.26

I upgraded to the latest version of Umbraco Contour (3.0.26). Now i get the following error:

Error loading MacroEngine script (file: MvcRenderContourForm.cshtml, Type: ''. Exception: System.Security.VerificationException: Operation could destabilize the runtime.

This is thrown in MvcRenderContourForm.cshtml, line 9:

@Html.RenderMvcAction(action, controller, formGuid, formtoken, (umbraco.MacroEngines.DynamicNode)Model, (System.Dynamic.DynamicObject)Parameter);

What could be the cause of this?

Solution

  • I found out that the oldVersion in bindingRedirect under assemblyBinding for System.Web.Mvc for some reason was set to 4.0.0.0-4.0.0.0 instead of 0.0.0.0-4.0.0.1. Fixing this set things straight.
