ASP.NET Routing using wrong route to generate URL; route values become query string parameters

Relevant route registration code:

routes.MapRoute(
  "QuestionsMostRecent",  
  "questions", 
  new { controller = "questions", action = "most_recent" }
);
routes.MapRoute(
  "ControllerActionFormat", 
  "{controller}/{action}.{format}"
);

Route generation code:

Url.RouteUrl(new {
  controller = "questions", 
  action = "most_recent", 
  format = "rss" 
});

I expect to receive "/questions/most_recent.rss", but instead I receive "/questions?format=rss". I realize I can force my expected result by referencing the route name "ControllerActionFormat", but I am curious about why exactly the routing system is matching the first route. Can anyone shed some light on this?

Because both of them match, but you have the more broadly defined route registered first. Register the more specific route first and it will solve the issue.
