MVC5 Attribute Routing with file extension

Question

Basically I am trying to use the new MVC5 routing attribute to redirect /sitemap.xml to a method as I need to dynamically create it.

// GET: /sitemap.xml
[Route("sitemap.xml")]
public ActionResult SiteMap()
{
    // Stuff
}

At the moment that doesn't work so is it possible to do it like this or will I have to use the routing table like I did before?

routes.MapRoute(
   name: "Site Map",
   url: "sitemap.xml",
   defaults: new { controller = "Default", action = "SiteMap" });

Well I've used that before with the correct result. You could try that runAllManagedHandlers flag to troubleshoot. If that doesn't work then something's weird somewhere. — ta.speot.is, Jan 19 '14 at 13:20
I don't suppose you have a route prefix at the controller level so it's not /sitemap.xml but /abcd/sitemap.xml ? — ta.speot.is, Jan 19 '14 at 13:21

Add this to your web.config:

 <system.webServer>
 <handlers>
      <add name="ManagedDllExtension" path="*.xml" verb="GET" type="System.Web.Handlers.TransferRequestHandler" preCondition="integratedMode,runtimeVersionv4.0" />
    </handlers>
</system.webServer>
