Question

This is for an ASP.NET MVC3 web application. In RegisterRoutes I have the following as my only line:

routes.MapRoute("Default", "Configuration", new { controller = "DeviceConfiguration", action = "Index" });

When I run the project, going to the URL /Configuration/ gives me a 404 error. However if I change the word Configuration to any other word, such as:

routes.MapRoute("Default", "Configuratio", new { controller = "DeviceConfiguration", action = "Index" });

Then going to the URL /Configuratio/ loads just fine. It seems as if ASP.NET is simply refusing to route to the URL /Configuration/.

Again, this is the only line in RegisterRoutes; I’ve tried commenting out everything else to debug this. I have no MapRoute or IgnoreRoute calls in my code anywhere else, and I am not editing the routing table in any location.

How can I change this behavior?

I suspect that you have a physical folder called Configuration under the root of your application. The ASP.NET MVC routing engine has preference for physical folders over routes. One possible way is to set the RouteExistingFiles property to true after your route definition:

routes.MapRoute(
    "Default", 
    "Configuration", 
    new { controller = "DeviceConfiguration", action = "Index" 
});
routes.RouteExistingFiles = true;
