MSMQ and TransactionScope

07 March 2012

It turns out that when using TransactionScope you should be creating the MessageQueue instance inside the TransactionScope:

using(var scope = new TransactionScope())
using(var queue = new MessageQueue(path, true))
{
	// timeout should be higher for remote queues
	// transaction type should be None for non-transactional queues

	var message = queue.Receive(TimeSpan.FromMilliseconds(0), MessageQueueTransactionType.Automatic);

	// ...normal processing...

	scope.Complete();
}

So MSMQ behaves the same way that a database connection does in that one has to create the database connection inside the scope.
