How to delete (waiting) bulk delete jobs using c# plugin - Dynamics365 (on-prem).

Hi All,

I need to delete unwanted bulk delete jobs(which is in waiting state) in dynamics365-on prem. Since I can delete only cancelled jobs. I am trying to change statuscode of bulk delete jobs from "waiting" to "canceled" using c#. 

Below screenshot shows my code.

Above code gets executed without any error but status code update is not happening. Please let me know the way to delete / cancel bulk delete jobs using c# plugin.

Thanks in advance.

Regards,

Swathi.
