Could you provide some code and what error you're getting?

Or you could create a starting class which inherits from UmbracoDefaultOwinStartup, if all else fails.

thanks Sibren. The exception is

Unable to resolve type: MyWebsite.WidgetsController, service name:

where the controller is

    [RoutePrefix("widgets")]
public class WidgetsController : Controller
{
    [ChildActionOnly]
    [Route("show")]
    public ActionResult Show()
    {
        return PartialView();
    }
}

and the view has

@Html.Action("Show", "Widgets")

Yes using Owin could be one option. Essentially I just want to register (the non umbraco) mvc routes in my application, so figured i need to call MapMvcAttributeRoutes somehow?

The Umbraco component is:

    public class RegisterCustomRouteComponent : IComponent
{
    public void Initialize()
    {
        RouteTable.Routes.MapMvcAttributeRoutes();
    }

    public void Terminate()
    {
        throw new NotImplementedException();
    }
}

update: following another thread i found, i made my controller inherit from RenderMvcController so that umbraco "knows" about the controller/"service".

Did this work? Because RouteTable.Routes.MapMvcAttributeRoutes(); does not what you're describing here.

It does map the routes you're using in your controller though. I am reading up on https://our.umbraco.com/documentation/reference/routing/custom-routes where it states you need to do some other stuff. Did you read that? I am trying the same thing but with an API, but am also struggling.

I'll keep you informed!

Hi - yes it worked. So at this point I have a Component that calls "RouteTable.Routes.MapMvcAttributeRoutes();" and also a custom controller that inherits from RenderMvcController.

This was the only way i could register the routes for my custom controller methods even though the methods aren't concerning umbraco content. I figure it makes sense that this is how an "UmbracoApplication" would know about all of the registered routes (umbraco or not). Ideally i wouldn't need to use RenderMvcController if there was some other/simpler way

basically, my original question was how do i get an UmbracoApplication to honour the stock standard mvc route attribute on my custom controller method:

        [Route("/my/custom/method")]
    public ActionResult MyMethod()

is working on a reply...
