I am using the .NET 3.5 SP1 framework and I’ve implemented URL routing in my application. I was getting javascript errors:

Error: ASP.NET Ajax client-side framework failed to load.
Resource interpreted as script but transferred with MIME type text/html.
ReferenceError: Can't find variable: Sys

Which I believe is because my routing is picking up the microsoft axd files and not properly sending down the javascript. I did some research and found that I could use Routes.IgnoreRoute, which should allow me to ignore the axd like below:

Routes.IgnoreRoute('{resource}.axd/{*pathInfo}');

But, when I add that line to my Global.asax I get this error:

CS1061: 'System.Web.Routing.RouteCollection' does not contain a definition for 'IgnoreRoute' and no extension method 'IgnoreRoute' accepting a first argument of type 'System.Web.Routing.RouteCollection' could be found (are you missing a using directive or an assembly reference?)

I’ve got the System.Web.Routing namespace imported, any ideas?

  1. 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.
