c# - Versioning using Attribute Routing in ASP .net WEB API -

i trying implement versioning using attributerouting in web api. have defined 2 folders under controllers called v1 , v2. have multiple controllers in each folder. in product controller define

routeprefix [routeprefix("v1/product")] , [routeprefix("v2/product")]

when go uri v1/product works fine, v2/product executes code in v1 folder. attribute routing support versioning or have related routes well. route defined

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

my product controller looks like

namespace api.controllers {  [routeprefix("v1/product")]   public class productv1controller : apicontroller  {      private dbcontext db = new dbcontext();        public dynamic get()     {        //gets products     } } 

the code in v2 product is

namespace api.controllers {  [routeprefix("v2/product")]   public class productv2controller : apicontroller  {      private dbcontext db = new dbcontext();        public dynamic get()     {        //gets products     } } 

can please suggest or provide link example implement versioning using attribute routing

you need decorate actions route attribute in order work.

[route] public dynamic get() ...

also, need have config.maphttpattributeroutes(); in webapiconfig's register method

update
