            //objClaimAudit.ClaimAudit_Name = "Claim1";
            //objClaimAudit.FromDate = DateTime.Now.AddYears(-1);
            //objClaimAudit.FromDate = DateTime.Now;
            return PartialView("_ClaimAuditAdminView");
        }



    }
}

I know this question has been asked many times,but after reading all those SO similar questions i am not able to track my error.I have put the debugger in My controller's Constructor(ClaimAuditAdminController) but debugger doesn't goes there.
My Route.Config is

public class RouteConfig
    {
        public static void RegisterRoutes(RouteCollection routes)
        {
            routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

            routes.MapRoute(
                name: "Default",
                url: "{controller}/{action}/{id}",
                defaults: new { controller = "ClaimAuditAdmin", action = "DisplayClaimAuditView", id = UrlParameter.Optional }
            );
        }

and the screen shot of my error is
