[TypeAccessException: Attempt by security transparent method 'Infragistics.Web.Mvc.HtmlHelperExtensions.Infragistics(System.Web.Mvc.HtmlHelper`1<!!0>)' to access security critical type 'System.Web.Mvc.HtmlHelper`1<TModel>' failed.

Assembly 'Infragistics.Web.Mvc, Version=3.15.2.1027, Culture=neutral, PublicKeyToken=7dd5c3163f2cd0cb' is marked with the AllowPartiallyTrustedCallersAttribute, and uses the level 2 security transparency model.  Level 2 transparency causes all methods in AllowPartiallyTrustedCallers assemblies to become security transparent by default, which may be the cause of this exception.]
