Do hangfire recurring jobs need to be in program.cs?

Question

I am using .Net 7 and Hangfire 1.8.5

Do all of hangfire's recurring jobs have to be listed directly in Program.cs ? Or can I abstract them out into a sub module? I'd rather have 20 recurring jobs in a seperate module than all in Program.cs

Program.cs :

app.UseHangfireDashboard();
app.MapHangfireDashboard();

// Hangfire Recurring Jobs
RecurringJob.AddOrUpdate<MyTestService>("Test Job", (x) => x.testJob("hangfire test 
job"), Cron.Daily(8, 30));
....to infitity...

Could I have instead...

Program.cs :

app.UseHangfireDashboard();
app.MapHangfireDashboard();

BackgroundJobs jobs = new BackgroundJobs();
jobs.MyRecurringJobs();

I assume I'd need to pass something into this new BackgroundJobs class? How would I setup hangfire to work this way?

`AddOrUpdate` is a static method on `RecurringJob`. Why would it matter where you call it from, so long as you call it? — ProgrammingLlama, Sep 01 '23 at 09:08
Also, if your storage is persistent, I don't think you need to call it every time your application starts. — ProgrammingLlama, Sep 01 '23 at 09:10
Did you try it first? You can put those calls anywhere you like. — DavidG, Sep 01 '23 at 09:44
I was after the standard practice example of how to use hangfire, DenisMichael.K's answer was what I was looking for. I didn't want to use it in a way no one else does. — Scottish Smile, Sep 02 '23 at 07:11

No, hangfire recurring jobs do not need to be in program.cs. As others have pointed out RecurringJob is a static class and can be called anywhere from your code.

However if you want to call it in program.cs separately. I would use a static class as below:

public static class HangfireWorker
{
  public static void StartRecurringJobs(this IApplicationBuilder app)
  {
   RecurringJob.AddOrUpdate("test_job", () => TestJob("hangfire test job"), 
            Cron.Daily(8, 30));
                    }
        //to infinity
}

Then in my program.cs proceed to call app.StartRecurringJobs();

Also incase you face issue jobstorage.Current not initialized on startup you might need to initialize the Jobstorage.Current

Thanks for the guidance! Every example I'd seen online was using them in program.cs and this reply shows me good standard practice of how to abstract them. — Scottish Smile, Sep 02 '23 at 07:09
