I have a custom Umbraco event handler class, that deals with ApplicationStarted/Initialized/Starting events, a long with published events. It also sets up all my dependency injection for my controllers.

All of a sudden, none of the events are being hit. I was previously inheriting my class from IApplicationEventHandler, and the ApplicationStarted event was being hit correctly. However I changed the file to inherit from ApplicationEventHandler and now nothing is firing. I tried changing it back to IApplicationEventHandler but no use, now no events are firing at all.

My code below:

public class UmbracoEventHandler : ApplicationEventHandler
{
    private static UmbracoApplicationBase _umbracoApplication;
    private static ApplicationContext _applicationContext;
    private static IContentService _contentService;
    private static IEntityDirector _entityDirector;
    private static ContentRepository _contentRepository;
    private static object _lockObj = new object();
    private static bool _ran = false; 

    public UmbracoEventHandler()
    {
        _entityDirector = new EntityDirector();
        _contentRepository = new ContentRepository(_entityDirector, umbraco.cms.businesslogic.member.Member.GetCurrentMember().LoginName);
    }

    protected override void ApplicationInitialized(UmbracoApplicationBase umbracoApplication, ApplicationContext applicationContext)
    {

    }

    protected override void ApplicationStarting(UmbracoApplicationBase umbracoApplication, ApplicationContext applicationContext)
    {
    }

    protected override void ApplicationStarted(UmbracoApplicationBase umbracoApplication, ApplicationContext applicationContext)
    {
        if (!_ran)
        {
          lock (_lockObj)
          {
            if (!_ran)
            {

                _applicationContext = applicationContext;
                _umbracoApplication = umbracoApplication;
                _contentService = ApplicationContext.Current.Services.ContentService;

                ConfigureUnity(GlobalConfiguration.Configuration);
                ConfigureApi(GlobalConfiguration.Configuration);

                Document.AfterPublish += Document_AfterPublish;
                Document.AfterDelete += Document_AfterDelete;

                _ran = true;
            }
          }
        }
    }

    private void Document_AfterDelete(Document sender, umbraco.cms.businesslogic.DeleteEventArgs e)
    {
        if (sender.ContentType.Alias == "BuyProperty" || sender.ContentType.Alias == "RentProperty")
        {
            _contentRepository.DeleteContent(sender);
        }
    }

    private void Document_AfterPublish(Document sender, PublishEventArgs publishEventArgs)
    {
        if (sender.ContentType.Alias == "BuyProperty" || sender.ContentType.Alias == "RentProperty")
        {
            _contentRepository.InsertOrUpdateContent(sender);
        }
    }

    private void ConfigureUnity(HttpConfiguration config)
    {
        UnityContainer unity = new UnityContainer();
        unity.RegisterType<PropertiesApiController>();
        unity.RegisterType<IEntityDirector, EntityDirector>(new HierarchicalLifetimeManager());
        config.DependencyResolver = new IoCContainer(unity);
    }

    private void ConfigureApi(HttpConfiguration config)
    {
        var appXmlType = config.Formatters.XmlFormatter.SupportedMediaTypes.FirstOrDefault(t => t.MediaType == "application/xml");
        config.Formatters.XmlFormatter.SupportedMediaTypes.Remove(appXmlType);
    }

I cant for the life of me figure out why none of the events have suddenly stopped firing. It's especially weird as previously they were firing fine.

Also, in my updated class, I have set breakpoints on all the methods, including the constructor, but it only ever makes it into the constructor, never the event methods.

Btw, I am using umbraco v6.1.1.

Thanks, Justin
