Hi,
The best solution is to create your own business object for that. Not sure what you would like to transfer through MQ, but you probably need another lib/object to parse the data too, I know it's very common to transfer SOAP and SWIFT data, and there is no good-objects available for that either
If it's not connected to any client issue I got tons of other options. Anyhow, I suggest you take a look at WebSphere MQ .NET if you want to develop a good object. The other solution is to simple create an object where you spy a WebSphere client, but I would say that is no good option... You want the dataflow to be simple and quick I suppose?
