Failed to set the expiration attribute of Hangfire.

Question

I use Hangfire to complete tasks, and I would like to change the behavior that deleted tasks are deleted from the database every other day — I would like them to be stored for a year.

Following the instructions in this thread , which matches this SO question , I created a class:

public class OneYearExpirationTimeAttribute : JobFilterAttribute, IApplyStateFilter
{
    public void OnStateUnapplied(ApplyStateContext context, IWriteOnlyTransaction transaction)
    {
        context.JobExpirationTimeout = TimeSpan.FromDays(365);
    }

    public void OnStateApplied(ApplyStateContext context, IWriteOnlyTransaction transaction)
    {
        context.JobExpirationTimeout = TimeSpan.FromDays(365);
    }
}

and I will register it in my api app.net startup class as a global filter:

public class Startup
{
    public void Configuration(IAppBuilder app)
    {
        // ... other stuff here ...
        GlobalJobFilters.Filters.Add(new OneYearExpirationTimeAttribute());
        GlobalConfiguration.Configuration.UseSqlServerStorage("HangFireDBConnection");
        app.UseHangfireDashboard();
    }
}

Web api is the place where vacancies are placed (i.e. a call is made BackgroundJob.Enqueue(() => ...)). I have not changed the configuration of clients who perform actual tasks.

Console, ,

static void Main(string[] args)
