I've run into an issue with a VB application using the .net interface. The application works fine on an XP environment, but run from an NT machine I get a failure on a PlatformNotSupportedException. My understanding is that with the MQ Client CSD5 (or greater) and the appropriate .net levels that NT platform (SP 6a) is a supported platform.
The application is using the MQ Client code through the .net classes included in the IBM install. We are not using the MQEnvironment settings as we need to specify our security exit, so we a forcing it to use the channel table instead. As I've said this works fine on XP (specifically XP Professional). On NT (SP 6a) however the error shows that the IBM.WMQ.MQQueueManger class in a method called IsMTSEnvironment() tries to use the System.enterpriseServices.ContextUtil.get_ContextID() which according to my documentation is only valid on XP and 2000 (and I would assume 2003 Server). So the question is has any body attempted anything like this? Do you know of a way around this? Or am I missing something about what is and is not supported? I have attempted to trace this but it showed nothing very enlightening, only an internal error in the tracing of the .net classes. I installed CSD6 on the clients on both machines. This fixed the trace error but did nothing for the exception. I've also tried this with the new CSD7 but still get the exception on NT. MQ Client is 5.3 (now CSD7). Dotnet framework is v1.1.4322. Operating system in NT4 sp6A. Any advice would be appreciated.
