How to ignore route in asp.net forms url routing
You don't need to reference ASP.NET MVC. You can use the StopRoutingHandler which implements IRouteHandler like so:
routes.Add(new Route("{resource}.axd/{*pathInfo}", new StopRoutingHandler()));This is part of .NET 3.5 SP1 and doesn't require MVC. The IgnoreRoutes method is a convenience extension method which is part of ASP.NET MVC.
An old question but in case it still helps anyone, this worked for me:
routes.Ignore("{resource}.axd/{*pathInfo}");The "Ignore" method exists, whereas in standard ASP.NET the "IgnoreRoute" method appears not to (i.e., not using MVC). This will achieve the same result as Haacked's code, but is slightly cleaner ...
I would just like to add that you also need to make sure the order of your IgnoreRoutes rule is in the the correct order otherwise your first route will be applied first and your IgnoreRoute will... well be ignored.
