If there is a System.Net.WebException error: retry up to 10 times with a 2 minute gap between each attempt.

[AviramDahan]

this ensures that your code will attempt to handle web exceptions by retrying the operation multiple times with a brief pause between each attempt, thus potentially mitigating transient network issues or temporary server glitches.

btw:
about this parameter: WorkItemCreateRetryLimit
I tried 0 and I tried 50,000, but it still stopped after 5 attempts due to connection issues.
