A'm using NMS.MSMQ for to produce messages to MSMQ
If i create session with AcknowledgementMode.AutoAcknowledge it throws NullPointerException at Dispose Method

Code

using (var connection = connectionFactory.CreateConnection())
{
using (var session = connection.CreateSession(AcknowledgementMode.Transactional))
{
var destination = SessionUtil.GetDestination(session, mailQueue);

using (IMessageProducer producer = session.CreateProducer())

{ producer.DeliveryMode = MsgDeliveryMode.Persistent; var request = session.CreateBytesMessage(Encoding.UTF8.GetBytes(serialized)); request.NMSType = "Test"; producer.Send(request, MsgDeliveryMode.Persistent, MsgPriority.Normal, TimeSpan.Zero); }

public MessageQueueTransaction MessageQueueTransaction
{
get

{ //---------------------------------------------------------------------------------------- // messageQueueTransaction is null with AutoAcknowledge mode //---------------------------------------------------------------------------------------- if(messageQueueTransaction.Status != MessageQueueTransactionStatus.Pending) messageQueueTransaction.Begin(); return messageQueueTransaction; }
