API versioning through namespace is explained here. Create a new HttpControllerSelector for yourself as described in the blog post and given example, then switch to that selector in your FilterConfig via:

GlobalConfiguration.Configuration.Services.Replace(typeof(IHttpControllerSelector), new NamespaceHttpControllerSelector(GlobalConfiguration.Configuration));

Then, register your routes:

config.Routes.MapHttpRoute(
  name: "VersionedApi",
  routeTemplate: "api/{version}/{controller}/{id}",
  defaults: new { id = RouteParameter.Optional }
);

config.Routes.MapHttpRoute(
  name: "DefaultApi",
  routeTemplate: "api/{controller}/{id}",
  defaults: new { id = RouteParameter.Optional }
);

In your custom HttpControllerSelector, if you want to fallback to a default version, then use the following:

string versionName = GetRouteVariable(routeData, "version");
versionName = versionName ?? DefaultVersion;
