- TState
The type of the state.
- TResult
The result type of the Task<TResult> returned by operation.
Parameters
- operation
- Func<TState,CancellationToken,Task<TResult>>
A function that returns a started task of type TResult.
- verifySucceeded
- Func<TState,CancellationToken,Task<Boolean>>
A delegate that tests whether the operation succeeded even though an exception was thrown when the transaction was being committed.
- state
- TState
The state that will be passed to the operation.
- cancellationToken
- CancellationToken
A cancellation token used to cancel the retry operation, but not operations that are already in flight or that already completed successfully.
Returns
A task that will run to completion if the original task completes successfully (either the first time or after retrying transient failures). If the task fails with a non-transient error or the retry limit is reached, the returned task will become faulted and the exception must be observed.
Exceptions
Thrown if the operation has not succeeded after the configured number of retries.
