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.
