c# - ASP.Net MVC IdentityServer3 broke my webapi routing -

so implementing security on project working on , followed guide identityserver3 add mvc5 application. got through complete setup , thought good, until realized routes in api, unless basic ones, /api/.../ no longer work.

     config.routes.maphttproute(             name: "defaultapi",             routetemplate: "api/{controller}/{id}",             defaults: new { id = routeparameter.optional }         ); 

i using default routing, , on various pieces of api controllers have put route attributes guide them in event fall outside of format. example:

    [route("api/location/getbyareaincludefilestore/{id}")]     public ienumerable<location> getlocationsbyareaidincludefilestore(int id)     {         if (id <= 0)         {             return null;         }         ienumerable<location> locations = _lookupservice.getlocationsbyareaidincludesfilestore(id);         return locations;     } 

and said earlier, prior adding identity server theses worked beautifully. during addition of identityserver had add few nuget packages webapi:

    install-package microsoft.owin.host.systemweb     install-package microsoft.aspnet.webapi.owin     install-package thinktecture.identityserver3.accesstokenvalidation 

so question after said , done is, how can fix routes can of information need?

currently have routes

    api/controller     api/controller/id     api/controller/action     api/controller/action/id 

any amazing, thanks! also, looked through many of other posts , tried lot of variations of routing , attributes before asking question.

add line in webapiconfig config.maphttpattributeroutes(); before config.routes.maphttproute().
