In the .NET MQ manual the statement:
'If you require simultaneous access to the same queue manager from multiple threads within your program, create a new MQQueueManager object for each thread that requires concurrent access. (This is equivalent to issuing a separate MQCONN call for each thread.)'
Is this really saying that even if you create a connection pool, you are still creating a separate connection for each thread? |

Yes. WMQ connections are not thread safe and can't be shared.

WMQ connections can be shared between threads as of a middling CSD of v5.3, or potentially v5.2. This does not necessarily mean they should be, or that a connection sitting in MQGET with WAIT will be usable by anyone else.
Getting a connection from a connection pool will provide you a connection out of the pool, that is yours until you return it.
If the pool has no free connections, it will create a new one if the pool size allows.
The behavior of the MQQueueManager constructor under .NET with a connection pool is left as an exercise for the reader. |

| I am using MQ 6.0. Not sure if that makes a difference. |
