Handlers returns 404 error on IIS7.5 integrated pipeline

Answer 1

After trying a lot of the options, they didn't work out. But however, this worked. In your Appstart folder add this code routes.IgnoreRoute("{resource}.axd/{*pathInfo}") in routeconfig.cs as shown below.

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