Definition

Overloads

ExecuteInTransactionAsync(IExecutionStrategy, Func<Task>, Func<Task<Boolean>>, IsolationLevel)

Executes the specified asynchronous operation in a transaction. Allows to check whether the transaction has been rolled back if an error occurs during commit.

ExecuteInTransactionAsync<TResult>(IExecutionStrategy, Func<CancellationToken, Task<TResult>>, Func<CancellationToken,Task<Boolean>>, IsolationLevel, CancellationToken)

Executes the specified asynchronous operation in a transaction and returns the result. Allows to check whether the transaction has been rolled back if an error occurs during commit.

ExecuteInTransactionAsync<TState,TResult>(IExecutionStrategy, TState, Func<TState,CancellationToken,Task<TResult>>, Func<TState, CancellationToken,Task<Boolean>>, IsolationLevel, CancellationToken)

Executes the specified asynchronous operation and returns the result. Allows to check whether the transaction has been rolled back if an error occurs during commit.

<Extension()>
Public Function ExecuteInTransactionAsync (strategy As IExecutionStrategy, operation As Func(Of Task), verifySucceeded As Func(Of Task(Of Boolean)), isolationLevel As IsolationLevel) As Task

Parameters

strategy
IExecutionStrategy

The strategy that will be used for the execution.

operation
Func<Task>

A function that returns a started task.

verifySucceeded
Func<Task<Boolean>>

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.

Parameters

strategy
IExecutionStrategy

The strategy that will be used for the execution.

operation
Func<CancellationToken,Task>

A function that returns a started task.

verifySucceeded
Func<CancellationToken,Task<Boolean>>

A delegate that tests whether the operation succeeded even though an exception was thrown when the transaction was being committed.

isolationLevel

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
