Public Function ExecuteInTransactionAsync (strategy As IExecutionStrategy, operation As Func(Of Task), verifySucceeded As Func(Of Task(Of Boolean)), isolationLevel As IsolationLevel) 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.
- isolationLevel
- IsolationLevel
The isolation level to use for the transaction.
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
See Connection resiliency and database retries for more information and examples.
