c# - Web API Routing conflict when adding PUT method to subroute, with multiple controllers -

i'm not sure how name problem. had difficulty searching particular issue reason. closest matching question found web api routing conflict 2 different controllers?.

like asker in question, have 2 different controllers partially match:

public class jobscontroller : apicontroller {     [responsetype(typeof(dtjob[]))]     public async task<httpresponsemessage> get()     {         //...     }      [route("v1/jobs/group"), responsetype(typeof(dtjob[]))]     public async task<httpresponsemessage> getfromgroup()     {         //...     }      [httpget, route("v1/jobs/{jobid}/status"), responsetype(typeof(string))]     public async task<httpresponsemessage> getstatus(long jobid)     {         //...     }      [httpput, route("v1/jobs/{jobid}/status"), responsetype(typeof(void))]     public async task<httpresponsemessage> updatestatus(long jobid, string status)     {         //...     }      //this method messes other controllers     [httpput, route("v1/jobs/{jobid}"), responsetype(typeof(void))]     public async task<httpresponsemessage> put(long jobid, dtjob job)     {         //...     }      //but works if replace above method default routing pattern:     //[responsetype(typeof(void))]     //public async task<httpresponsemessage> put(long id, dtjob job)     //{     //    //...     //} } 

and controller has similar prefix:

[routeprefix("v1/jobs/materials")] public class materialscontroller : apicontroller {     [route, responsetype(typeof(dtmaterial[]))]     public async task<httpresponsemessage> get()     {         //...     } } 

and routing configs:

public class routeconfig {     public static void registerroutes(routecollection routes)     {         routes.ignoreroute("{resource}.axd/{*pathinfo}");         routes.mapmvcattributeroutes();     } }  public static class webapiconfig {     public static void register(httpconfiguration config)     {         //...         // web api routes         config.maphttpattributeroutes();         //...         config.routes.maphttproute(             name: "newest",             routetemplate: "v1/{controller}/{id}",             defaults: new { id = routeparameter.optional }         );     } } 

what's going on here?

i think found issue again. since {jobid} not specified in type, potentially string says "materials", creating conflict. resolve this, specify type in parameter ({jobid:long}):

    [httpput, route("v1/jobs/{jobid:long}"), responsetype(typeof(void))]     public async task<httpresponsemessage> put(long jobid, dtjob job)     {         //...     }
