ExecuteInTransactionAsync(IExecutionStrategy, Func<Task>, Func<Task<Boolean>>)
Executes the specified asynchronous operation in a transaction. Allows to check whether the transaction has been rolled back if an error occurs during commit.

Public Function ExecuteInTransactionAsync (strategy As IExecutionStrategy, operation As Func(Of Task), verifySucceeded As Func(Of Task(Of Boolean))) As TaskParameters
- strategy
- IExecutionStrategy
The strategy that will be used for the execution.
A delegate that tests whether the operation succeeded even though an exception was thrown when the transaction was being committed.
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
The operation has not succeeded after the configured number of retries.
Remarks
