I am using Umbraco v 7.7.9. I have a class that listens for the unpublished event firing and performs some actions when it does. It works perfectly when content nodes are manually unpublished however, when I set content for scheduled unpublish it is not picked up. Here's my code:

    protected override void ApplicationStarted(UmbracoApplicationBase umbracoApplication, ApplicationContext applicationContext)
    {
        // Hook on to the content node unpublish event firing
        ContentService.UnPublished += ContentServiceUnPublished;
    }

    private void ContentServiceUnPublished(IPublishingStrategy sender, PublishEventArgs<IContent> args)
    {
        // Do something 
    }

Should this be the case? And if it is, is there something else I can do to pick up scheduled unpublish?

Thank you in advance.
