| Does anyone know whether or not the .NET MQ classes contain unmanaged code? For example, if I access the MQ .NET APIs through a .NET ServicedComponent running in COM+, do I need to call Marshall.ReleaseCOMObject() instead of calling Dispose()? I am hoping that the IBM code in amqmdnet.dll is cleaning up resources correctly if there is unmanaged code being used. |

Depends on the version. The older versions of the .NET API are just a wrapper around the C code.
The latest version I believe is written entirely in .NET managed code.
Enjoy

The latest FP of v6 (FP3) includes a fully managed client connection option.
Server bindings are unchanged.
I do not know if the "managed client" option has anything to do with the "managed code" portion of this question.

| I thought we were only up to CSD2 for the MQ Client for Windows? Is there a CSD3? |

My understanding is that although the 5.3 (and 6.0 by default) classes call through to the C layer, it should not make any changes to the application to handle this, ie normal disposing rules apply.
For v6 dont get confused trying to have a sequential 1,2,3... fixpack or csd notation, its gone 4 digit and its best to refer to the whole 4 digits.
At 6.0.2.0 there is a fully managed option which builds and sends the flows to the server itself - note it may still call through to the C code however for some common services functions (eg. trace) and its not supported standalone (ie outside of an MQ installation). |

| Ok thanks for the tip. I am in the process of installing 6.0.2.0. The application that I am working on will actually connect to queues that run on a UNIX server through the MQ client. I do not have WebSphere running on the same box. |
