I was able to get it working. Not sure if there is a better way or not, but I found a Umbraco JavaScript function [UmbClientMgr.content (url)] that provided a way to get it to work. The only issue I am having now is that the function causes the "spinner" to show and I have not figured out how to get rid of it. If you know how to remove it, please let me know.

THE SHORT VERSION of getting it to work is to use the page in your Dashboard.config file as a relay to load your MVC page.

In your Dashboard.config:

Then in LaodDefault.html,

<script>
    UmbClientMgr.contentFrame("/umbraco/backoffice/Plugins/AgentAdmin/AgentProfile");
</script>

THE LONG VERSION is posted below. I would have preferred to post this in a zip, but that is not an available option.

RouteConfig.cs

using System.Web.Mvc; using System.Web.Routing;

namespace YourProject.AppPlugins.AgentAdmin.AppStart { public class RouteConfig { public static void RegisterRoutes(RouteCollection routes) { routes.IgnoreRoute("{resource}.axd/{*pathInfo}"); RouteTable.Routes.MapRoute( "AgentAdmin", "umbraco/backoffice/Plugins/AgentAdmin/{action}/{id}", new { controller = "AgentAdmin", action = "AgentProfile", id = UrlParameter.Optional }); } } }

WebApiConfig.cs

using System.Web.Http;

namespace YourProject.AppPlugins.AgentAdmin.AppStart { public static class WebApiConfig { public static void Register(HttpConfiguration config) { config.Routes.MapHttpRoute( name: "DefaultApi", routeTemplate: "api/{controller}/{id}", defaults: new { id = RouteParameter.Optional } ); } } }

AgentProfileController.cs

using System; using System.Web.Mvc; using Umbraco.Web.Mvc;

namespace YourProject.App_Plugins.AgentAdmin.Controllers { public class AgentAdminController : UmbracoAuthorizedController { public ActionResult AgentProfile() { try { Agent agent = new Agent(); agent.FirstName = "Mickey"; agent.LastName = "Mouse";

            return View("~/App_Plugins/AgentAdmin/Views/AgentProfile.cshtml", agent);
        }
        catch (Exception ex)
        {
            throw;
        }

    }


}

}

@model Agent

Hello @Model.FirstName @Model.LastName
