>Yup...that's it...and I agree completely. Not sure how much "new" development you're doing, but I found a pdf on IBM's site describing how to use .Net with MQSeries. Don't remember the url but if you want a copy, I can email it to you?

Right now, we use IBM WebSphere MQ Client 5.3. This is very old. Do you know if there is a newer client elsewhere we could use? As I have to reinstall that component on the server, I might as well try to get an updated version.
