I have WebSphere MQ 1.0.0.3. This is the file amqmdnet.dll. This is dated from December 13th, 2004. This component has been used in a previous version of .NET. Now, I need to plug that into our new version, which is under .NET 4. However, I have the feeling this is not compliant. Has anyone succeeded to use that version under .NET 4? Or, any suggestion on the download to be more up to date?

Because, when I do this:

        Dim loMQEnvironment As IBM.WMQ.MQEnvironment

        ' Define environment variables
        loMQEnvironment.Hostname = Trim(oApp.oAdmin.oRow("MQIP"))
        loMQEnvironment.Channel = Trim(oApp.oAdmin.oRow("MQChannel"))
        loMQEnvironment.Port = oApp.oAdmin.oRow("MQPort")

...it says some warnings such as:

"Access of shared member, constant member, enum member or nested type through an instance; qualifying expression will not be evaluated."
