Hi Carl,

you can set the default render item, in a Composer . (which is part of the new startup routines) - your RenderController needs to implement IRenderMvcController (which is auto-discovered so you don't need to add that explicity to a composition)

public class MyComposer : IUserComposer
{
    public void Compose(Composition composition)
    {
        composition.SetDefaultRenderMvcController(typeof(MyMvcController));
    }
}

public class MyMvcController : IRenderMvcController
{
    public void Execute(RequestContext requestContext)
    {
        throw new NotImplementedException();
    }

    public ActionResult Index(ContentModel model)
    {
        throw new NotImplementedException();
    }
}
