If my understanding is correct with Umbraco 7 we can't have global.asax file. I have to handle asp.net's application error event and log errors. I follow this link and hock umbracoApplication.Error event.

Issue is, on error this event is not firing. When I run application I can see umbracoApplication.Error is regestered but throwing an error in MVC action do not come here. Please help me.

My MVCStartup.cs is below:

 public class MyStartupHandler : IApplicationEventHandler
{
    public void OnApplicationStarted(
        UmbracoApplicationBase umbracoApplication,
        ApplicationContext applicationContext)
    {
        //Create a custom route
        RouteTable.Routes.MapRoute(
            "HealthInsurance",
            "HealthInsurance/{action}/{id}",
            new
            {
                controller = "HealthInsurance",                    
                id = UrlParameter.Optional
            });

        RouteTable.Routes.MapRoute(
          "HomeLoan",
          "HomeLoan/{action}/{id}",
          new
          {
              controller = "HomeLoan",                  
              id = UrlParameter.Optional
          });

        RouteTable.Routes.MapRoute(
          "LifeInsurance",
          "LifeInsurance/{action}/{id}",
          new
          {
              controller = "LifeInsurance",
              action = "Index",
              id = UrlParameter.Optional
          });

        RouteTable.Routes.MapRoute(
         "EDM",
         "EDM/{action}/{id}",
         new
         {
             controller = "EDM",
             action = "Index",
             id = UrlParameter.Optional
         });

        RouteTable.Routes.MapRoute(
       "AFFILIATE",
       "AFFILIATE/{action}/{id}",
       new
       {
           controller = "AFFILIATE",
           action = "Index",
           id = UrlParameter.Optional
       });        


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

    void umbracoApplication_Error(object sender, System.EventArgs e)
    {
        throw new Exception("Test MVc Umbraco Error");
    }
    public void OnApplicationInitialized(
        UmbracoApplicationBase umbracoApplication,
        ApplicationContext applicationContext)
    {
    }
    public void OnApplicationStarting(
        UmbracoApplicationBase umbracoApplication,
        ApplicationContext applicationContext)
    {
        umbracoApplication.Error += umbracoApplication_Error;
    }
}

1. My Global.asax file has only below line but no Codebehind class is there.

   <%@ Application Codebehind="Global.asax.cs" Inherits="Umbraco.Web.UmbracoApplication" Language="C#" %>

2. Controller & Action is below:

public class LandingController : Umbraco.Web.Mvc.RenderMvcController
{       
    [OutputCache(Duration=300)]
    public ActionResult uLanding(Landing model)
    {
        throw new Exception();
        return base.Index(model);
    }

}
