c# - Existing asp.net project no new controller function is working, showing 404 -

i working on existing asp.net website , code client server code hosted. able run project in local pc when try add new controller function show http 404. ![enter image description here][1]

for example in accountcontroller.cs there existing login function

    // get: /account/login      [allowanonymous]     public actionresult login(string returnurl)     {         if (websecurity.isauthenticated == true){             websecurity.logout();             session.abandon();         }         viewbag.returnurl = returnurl;         return view();     } 

then copied function , created new 1 below , duplicated view file , renamed

    //     // get: /account/aalogin     [allowanonymous]     public actionresult aalogin(string returnurl)     {         if (websecurity.isauthenticated == true)         {             websecurity.logout();             session.abandon();         }         viewbag.returnurl = returnurl;         return view();     } 

global.asax.cs

    public static void registerroutes(routecollection routes)     {         routes.ignoreroute("{resource}.axd/{*pathinfo}");         routes.maproute(             "default", // route name             "{controller}/{action}/{id}", // url parameters             new             {                 controller = "home",                 action = "index",                 id = urlparameter.optional             });         routes.maproute(             "aalogin", // route name             "account/aalogin", // url parameters             new             {                 controller = "account",                 action = "aalogin",                 id = urlparameter.optional             });     } 

routeconfig.cs

        public static void registerroutes(routecollection routes) {          routes.ignoreroute("{resource}.axd/{*pathinfo}");          routes.maproute(             name: "viewlistingnoauth",             url: "{id}",             defaults: new { controller = "listing", action = "publicview"}         );          routes.maproute(             name: "socialmediahooks",             url: "externalservice/uploadflyertosocialmedia/{id}/{sname}",             defaults: new { controller = "home", action = "index", id = urlparameter.optional, name = urlparameter.optional }         );          routes.maproute(             name: "default",             url: "{controller}/{action}/{id}",             defaults: new { controller = "home", action = "index", id = urlparameter.optional }         );     } 

but still doesn't work when browse /account/aalogin... body can me in or resource can understand.

if can give me idea whats happening happy.

here few troubleshooting steps can try:

1. observe call in fiddler. call being fired? if so, match expecting?
2. install routedebugger (using nuget) , enable it. great tool see what's going on routes. tell routing rules being hit.

p.s. may want use 1 of "asp.net-mvc" tags similiar questions.
