WebApi Attribute routing is not working with Sitecore 7.5

If you are into WebApi, you were very excited to get attribute routing working on Sitecore 7.2…

you can read about it in several blogs and it works pretty well:



Unfortunately in Sitecore 7.5 rev. 141003 attribute routing it is not working anymore…. you can read more about it here

and this is the error that you would get:

Message: An error has occurred.
ExceptionMessage: Value cannot be null. Parameter name: key", ExceptionType: "System.ArgumentNullException", StackTrace: " at System.Collections.Generic.Dictionary2.FindEntry(TKey key) at System.Collections.Generic.Dictionary2.TryGetValue(TKey key, TValue& value) at Sitecore.Services.Infrastructure.Web.Http.Dispatcher.NamespaceHttpControllerSelector.SelectController(HttpRequestMessage request) at System.Web.Http.Dispatcher.HttpControllerDispatcher.SendAsyncCore(HttpRequestMessage request, CancellationToken cancellationToken) at System.Web.Http.Dispatcher.HttpControllerDispatcher.d__0.MoveNext() 

so my advice if, you want to use WebApi with Sitecore 7.5 is to have something like it:

url: api/Sdbother/getid

public class SdbotherController : ApiController
   public string GetId()
     return "test";

make the global.asax inherits from the following class:

public class GlobalExtended : Sitecore.Web.Application
   protected void Application_Start(object sender, EventArgs e)

  public static void ConfigureRoutes(HttpConfiguration config)
     new { id = RouteParameter.Optional });

    GlobalConfiguration.Configuration.Formatters.Add(new JsonMediaTypeFormatter());
