Hangfire Umbraco Example

A minimal example using Hangfire with Cultiv.Hangfire in Umbraco that:

1. Dynamically schedules tasks based on a notification

   Startup.cs:

   services.AddUmbraco(_env, _config)
     //...
     .AddNotificationHandler<ContentPublishingNotification, RegisterHangfire>
     //...

   RegisterHangfire.cs:

   RecurringJob.AddOrUpdate<ServiceThatUsesUmbracoContext>(x => x.DoSomethingWithUmbracoContext() , "* * * * *");

2. Does something with an UmbracoContext

   ServiceThatUsesUmbracoContext.cs:

   public void DoSomethingWithUmbracoContext()
   {
       using (var ctxRef = ctxFactory.EnsureUmbracoContext())
       {
           var contentAtRoot = ctxRef.UmbracoContext.Content!.GetAtRoot();
   
           var ids = string.Join(", ", contentAtRoot.Select(x => x.Id));
   
           Console.WriteLine($"Content IDs at root: {ids}");
       }
   }

Testing

1. Clone, and run.
2. In the installer choose a DB type supported by Hangfire (SQL or LocalDb)
3. Let the installer run (starter kit will be installed)
4. Stop & start the site.
   (There's a bug in the HangfireComposer that I've partially fixed but need to spend more time looking at)
5. Publish some content
6. Check it works - in the console, or set a breakpoint.
