c# - ASP.NET MVC service route overrides default route -

i have added wcf service mvc 5 application, , created route it:

public static void registerroutes(routecollection routes) {     routes.ignoreroute("{resource}.axd/{*pathinfo}");     routes.add(new serviceroute("service1.svc", new servicehostfactory(), typeof(service1)));     routes.maproute(         name: "default",         url: "{controller}/{action}/{id}",         defaults: new { controller = "home", action = "index", id = urlparameter.optional }     ); } 

the problem links leads service1.svc route now. @html.actionlink("passport maker", "index", "home", new { area = "" }, new { @class = "navbar-brand" }) become http://localhost:50099/service1.svc?action=index&controller=home , other links change in same way.

if add serviceroute after "default" route, links work correctly service unavailable.

why happens (there no "service1" in links, why select service route then?) , how fix it?

the solution:

routes.maproute(     name: "default",     url: "{controller}/{action}/{id}",     defaults: new { controller = "home", action = "index", id = urlparameter.optional },     constraints: new { controller = "^(?!service1.svc).*" } );  routes.add(new serviceroute("service1.svc", new servicehostfactory(), typeof(service1))); 

explanations may encounter similar problem: reason of problem html.actionlink uses first matching route generate link. , service route first , matching, because route not require include {controller} , {action} parameters matched (as thought initially).

the solution put default route first, used html.actionlink. , still able use service route, need exclude the first route using constraints. regex ^(?!service1.svc).* matches controller names don't start "service1.svc".
