MVC Style Bindings - Multiple actions were found ERROR

[freeranger]

If I have a controller with two GET actions - e.g /api/get and /api/get/:id, when I add [MvsStyleBinding] to my controller, I get the following error:

An error has occurred.
ExceptionMessage: Multiple actions were found that match the request: 
Get on type MvcStyleBindingProblem.ValuesController
GetById on type MvcStyleBindingProblem.ValuesController
ExceptionType:System.InvalidOperationException
StackTrace:  at System.Web.Http.Controllers.ApiControllerActionSelector.ActionSelectorCacheItem.SelectAction(HttpControllerContext controllerContext)
   at System.Web.Http.Controllers.ApiControllerActionSelector.SelectAction(HttpControllerContext controllerContext)
   at System.Web.Http.ApiController.ExecuteAsync(HttpControllerContext controllerContext, CancellationToken cancellationToken)
   at System.Web.Http.Dispatcher.HttpControllerDispatcher.<SendAsync>d__1.MoveNext()

I have a very simple api project here demonstrating the problem:

If I remove the[MvcStyleBinding] then the error goes away but obviously the whole point is to actually use it ;)
