svn commit: r1483919 - /activemq/activemq-dotnet/Apache.NMS.ActiveMQ/trunk/src/main/csharp/NetTxMessageConsumer.cs

[ta...@apache.org]

Author: tabish

New Revision: 1483919

URL: http://svn.apache.org/r1483919
Log:
fix for: https://issues.apache.org/jira/browse/AMQNET-419

Begins to partition the DTC ugliness into a NetTXMessageConsumer so we don't have to impact performance of the non-DTC consumer in order to deal with all DTC's issues.
