    Custom Routes - MapRoute - Error: Unable to resolve type: XXX.SurfaceControllers.JobQueueRunnerController, service name:


    I need to set-up a custom MapRoute so I can set a VisualCron task to periodically call the url and let it kick off a database check / email function.

    Either I'm losing the plot, or I've messed something up. This used to work in V7 in ApplicationEventHandler and a simple MapRoute.

    I understand that ApplicationEventHandlers are now out for V8, so I have the following:

    RegisterCustomRouteComposer in the root of the Umbraco project:

    public class RegisterCustomRouteComposer : ComponentComposer<RegisterCustomRouteComponent>
    public class RegisterCustomRouteComponent : IComponent
        public void Initialize()
            RouteTable.Routes.MapRoute("JobQueueRunner", "runjobqueue", new
                controller = "JobQueueRunner",
                action = "ProcessQueue",
                id = UrlParameter.Optional
        public void Terminate()
            throw new NotImplementedException();

    Then a JobQueueRunnerController (SurfaceController folder) and Interface to the JobQueueService

    public class JobQueueRunnerController : Controller
        private readonly IJobQueueService _jobQueueService;
        public JobQueueRunnerController(IJobQueueService jobQueueService)
            _jobQueueService = jobQueueService;
        public ActionResult ProcessQueue()
            return Content("Ok");
    public interface IJobQueueService
        void ProcessNextJobs(ControllerContext controllerContext);

    When http://<--sitename-->/runjobqueue is called, I get the following exception:

    [InvalidOperationException: Unable to resolve type: XXX.SurfaceControllers.JobQueueRunnerController, service name: ]
       LightInject.ServiceContainer.CreateDelegate(Type serviceType, String serviceName, Boolean throwError) +212

       System.Web.HttpApplication.ExecuteStepImpl(IExecutionStep step) +213
       System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously) +131

    Any ideas / pointers / obvious mistakes on my part?

    Hi Alastair.

    Could it be that JobQueueRunnerController should inherit from SurfaceController instead of Controller?

    public class JobQueueRunnerController : Umbraco.Web.Mvc.SurfaceController

    Have you installed your IJobQueueService in an IUserComposer?

        using Umbraco.Core;
        using Umbraco.Core.Composing;
        namespace My.Website
            public class CustomComposer : IUserComposer
                public void Compose(Composition composition)
                    composition.Register<IJobQueueService, JobQueueService>();

    Hi Bo,

    Thanks! I changed the controller to a SurfaceController and everything started working as I expected.

    I'd lifted the JobQueueRunnerController code straight from a working Umbraco7 site, which was happily working with just inheriting from 'Controller' and expected it to work...

    Thanks again.
