Parameters
Name Description
expiration Expiration

The expiration to use in order to know when to stop polling. Must not be null.
delay TimeSpan

The delay between RPC calls. Must be non-negative.
delayMultiplier double

The multiplier to apply to the delay on each iteration; must be greater or equal to 1.0.
maxDelay TimeSpan

The maximum delay to use.

Properties

Delay

The delay between RPC calls when fetching the operation status. This is never negative. There is no exponential backoff between calls; the same delay is used for each call.

Property Value
Type Description
TimeSpan

This is the delay between the a successful RPC response being received and the next RPC request being sent.

DelayMultiplier

public double DelayMultiplier { get; }

The multiplier to apply to the delay on each iteration; must be greater or equal to 1.0.

Type Description
double

Expiration

public Expiration Expiration { get; }

How long to wait before giving up. This is never null.
