Remarks

When you read or write a message using an overload of the MessageQueue class's Send or Receive methods (including ReceiveById and ReceiveByCorrelationId) that takes a transactionType parameter, you can specify how you are interacting with the queue. Automatic enables you to send and receive from external transactions (such as when you are interacting with database applications), while Single is used for single internal Message Queuing transactions.

None enables you to receive a message from a transactional queue outside of a transaction or send a transactional message to a nontransactional queue. This is useful, for example, when routing several messages sent within a single transaction.

If you want to send or receive a message using an internal Message Queuing transaction but not a single internal transaction, create an instance of the MessageQueueTransaction class and pass it into an overload of the Send or Receive methods that takes a transaction parameter rather than one that takes a transactionType parameter.
