    Adding Application Startup code

    Hi 

    I am new to Umbraco but enjoying it however I have a really frustrating problem. I am trying to fire code on the application startup event to register Routes and other things. After building the application and browsing Umbraco CMs everything works fine. Howver when I look at my site it is completely blank and no markup is being rendered in the page source. I am using the ApplicationEventHandler Base class to override the started event but nothing is working. After looking at the event viewer I see the following message:

    Process information: 

        Process ID: 13160 

        Process name: iisexpress.exe 

        Account name: MACKIEVISTA\danny 

     

    Exception information:

    My class file running the Started code (which is in the App_Code folder) is as follows
    using System;
    using System.Collections.Generic;
    using System.Linq;
    using System.Web;
    using System.Web.Http;
    using System.Web.Mvc;
    using System.Web.Routing;
    using Umbraco.Web;
    using Umbraco.Core;
    using System.Web.Optimization;
     
    namespace AmaUmbraco.Global
    {
        public class AMAGlobal : ApplicationEventHandler
        {
     
            protected override void ApplicationStarted(UmbracoApplicationBase umbracoApplication, ApplicationContext applicationContext)
            {
                base.ApplicationStarted(umbracoApplication, applicationContext);
                AreaRegistration.RegisterAllAreas();
     
                WebApiConfig.Register(GlobalConfiguration.Configuration);
                FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
                RouteConfig.RegisterRoutes(RouteTable.Routes);
            }
        }
    }
    I am using VS2012 Ultimate, Umbraco 7 and building an MVC 4 website using RAZOR. Please can someone help me ou there. I have wasted hour after hour looking at this and can't figure out why the umbracoContext parameter is null and causing this issue. I have looked at all of the articles I can find on this and tried all manner of different approaches but still the same result.

    Hi All

    Looks like this may have been a newby mistake. After closer investigation I thought maybe the reason nothing would render was due to my routing table in some way. So I have taken a look and realised that the default MVC route was still being registered as below

        public class RouteConfig
    {
        public static void RegisterRoutes(RouteCollection routes)
        {
            routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

            routes.MapRoute(
                name: "Default",
                url: "{controller}/{action}/{id}",
                defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
            );
        }
    }

     Once I removed my default route and replaced it with my contact controller route everything started to work perfectly.

            public static void RegisterRoutes(RouteCollection routes)
        {
            routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

            routes.MapRoute(
                name: "Default",
                url: "ContactUs/{action}/{id}",
                defaults: new { controller = "ContactUs", action = "Index", id = UrlParameter.Optional }
            );
        }

    As umbraco has it's own routing, my custom route was interfeering with Umbraco' main controller and causing things to fail. I hope this will help some other newbies to the world of Umbraco.
