Hello,

I'm in the process of trying to do a quick Umbraco 7.15.4 to Umbraco 8.15.0 upgrade and I'm getting an error when running via Visual Studio after I've upgraded all of the packages and fixed references.

I've tried the suggestions mentioned below:

• Make sure global.asax exist: https://our.umbraco.com/forum/using-umbraco-and-getting-started/97880-no-factory-has-been-set

• Build + clean and then build again: https://our.umbraco.com/forum/using-umbraco-and-getting-started/102571-862-new-install-no-factory-has-been-set Neither of those seemed to work.

Global.asax contents:

<%@ Application Inherits="Umbraco.Web.UmbracoApplication" Language="C#" %>

I'm wondering if maybe I have an error in my \App_Start\UmbracoEventsHandler.cs file after I migrated to the new format for components and composers? UmbracoEventsHandler.cs file:

using System;
using System.Web.Http;
using System.Web.Optimization;
using Umbraco.Core;
using Umbraco.Core.Composing;


namespace ProjectSite.App_Start
{
    public class ApplicationComposer : ComponentComposer<ApplicationComponent>, IUserComposer
    {
        public override void Compose(Composition composition)
        {
            // ApplicationStarting event in V7: add IContentFinders, register custom services and more here
            GlobalConfiguration.Configure(WebApiConfig.Register);

            composition.Components().Append<ApplicationComponent>();

            base.Compose(composition);
        }
    }

    public class ApplicationComponent : IComponent
    {
        public void Initialize()
        {
            // ApplicationStarted event in V7: add your events here
            BundleConfig.RegisterBundles(BundleTable.Bundles);
            GlobalConfiguration.Configuration.Formatters.JsonFormatter.MediaTypeMappings.Add(new System.Net.Http.Formatting.RequestHeaderMapping("Accept",
                              "text/html",
                              StringComparison.InvariantCultureIgnoreCase,
                              true,
                              "application/json"));
        }

        public void Terminate()
        { }
    }
}
