Properties
DeltaBackOff
public TimeSpan DeltaBackOff { get; }Gets the delta time span used to generate a random milliseconds to add to the next back-off. If the value is then the generated back-off will be exactly 1, 2, 4, 8, 16, etc. seconds. A valid value is between zero and one second. The default value is 250ms, which means that the generated back-off will be [0.75-1.25]sec, [1.75-2.25]sec, [3.75-4.25]sec, and so on.
