Answer by Simon_Weaver for Disable re-queueing of failed Hangfire BackgroundJob

Important if using DI container with an interface, you must put the attribute on the interface definition or it won't be recognized.

public interface IDataUpdater{    [Hangfire.AutomaticRetry(Attempts = 0, OnAttemptsExceeded = AttemptsExceededAction.Delete)]    void UpdateData();}

Queue the job like this

Hangfire.RecurringJob.AddOrUpdate<IDataUpdater>(updater => updater.UpdateData(), Cron.Hourly);

Test it with throw new Exception("Test!") within your implementation. If you've done it right you'll see this in the job history under 'deleted'.
