I believe I had found a bug in contour in umbraco v 4.8.

This issues follows one raised here:

http://our.umbraco.org/forum/umbraco-pro/contour/38943-Error-Service-Endpoint-not-found-on-submit

When an umbraco website uses routing (in web.config)

<system.serviceModel>
    <serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true" />
  </system.serviceModel>  

and a route is registered on application start up (like this in app_code) .. 

using System.ServiceModel.Activation;
using System.Web.Routing;
using umbraco.BusinessLogic;
using Umbraco.Web;
using Umbraco.Core;
public class AddRouteTest : IApplicationEventHandler
{
    private static object _lockObj = new object();
    private static bool _ran = false;
    public void OnApplicationStarted(UmbracoApplication httpApplication, ApplicationContext applicationContext)
    {
        // lock
        if (!_ran) {
            lock (_lockObj) {
                if (!_ran) {
                    RouteTable.Routes.Add(new ServiceRoute("my/custom/route", new WebScriptServiceHostFactory(), typeof(object)));
                    _ran = true;
                }
            }
        }
    }
    public void OnApplicationInitialized(UmbracoApplication httpApplication, ApplicationContext applicationContext) {}
   public void OnApplicationStarting(UmbracoApplication httpApplication, ApplicationContext applicationContext) {}
}

.. the <form> tag rendered on a form (using the razor macro ) is added incorrectly like this:

<form action="/my/custom/route?action=ContourForm&amp;controller=FormRender" enctype="multipart/form-data" method="post">

I think I have found a solution which is to modify the umbraco\plugins\umbracoContour\views\form.cshtml to render the form tag differently (from line 25)

@* ** THIS BREAKS** using (Html.BeginForm("ContourForm", "FormRender", FormMethod.Post, new { enctype = "multipart/form-data" })) ** SO USE INSTEAD ** *@
@using (Html.BeginForm())

Is this a bug with contour? A known issue that routing cannot be used on umbraco sites? or am I registering my custom route incorrectly?
