Hi everybody,

We upgraded the project to the latest MVC (and other packages to the latest) and now we are unable to run the application. The error comes from the

routes.MapMvcAttributeRoutes(); method in the RouteConfig class and the error is

Exception Details: System.ArgumentException: Cannot call action method 'System.Web.Mvc.PartialViewResult ErrorView[T](T, System.String, System.String, System.String)' on controller 'SysManager.Web.Areas.AccountingAudit.Controllers.PaymentTypesController' because the action method is a generic method.
Parameter name: methodInfo

Source Error:


Line 14: routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
Line 15:
Line 16: routes.MapMvcAttributeRoutes();
Line 17:
Line 18: AreaRegistration.RegisterAllAreas();

Source File: c:\_Siriusware\Main\SysManager\SysManager.Web\App_Start\RouteConfig.cs Line: 16

Stack Trace:

Do you know what should be fixed to make it work? Can you check what do you have in that class?

Thanks in advance.
