asp.net mvc 4 - ApiController routing seems to ignore action -

with routing defined in routeconfig.cs

  routes.maproute(     name: "default",     url: "{controller}/{action}/{id}",     defaults: new { controller = "durandal", action = "index", id = urlparameter.optional }     ); 

i expected http://localhost:50441/api/induction/getintro/4108 parse

controller = inductioncontroller action = "getintro" id = 4108 

and call getintro method of class

using system.web.http;  namespace mymvcapp.controllers {   public class inductioncontroller : apicontroller   {         public object getintro(int inductionid)     {            //simplified brevity           return new {         title = "foo",         text = "some introductory blather"       };     }   } } 

but doesn't. 404 not found, , burning question why.

most samples seem use maphttproute instead of maproute, maproute being extension method wraps maphttproute.

i confused existence of routeconfig.cs defines routes. works this:

• webapi routes configured webapiconfig.cs
• mvc routes configured routeconfig.cs
• you both because it's mvc project support webapi.

in project route defined in webapiconfig.cs api\{controller}\{id} , preceding route api\{controller}\{action}\{id} resolved problem.

the template generated crud methods worked because match api\{controller}\{id}
