Maybe I am missing something here but I don't see when InternalGetMetaData is called.

 

I am running with the test harness utility and debugging the DLL.  Does that method only get called with the real IOM?

Glad you're getting some testing in on it. The test harness just calls the run on the adapter. You could update the test adapter code to call InternalGetMetaData if you wanted (IOM will call it and each adapter can call as needed - e.g. for configuration, etc.). Or we can probably update the TestHarness app with an additional option to "Show Metadata" or something of that nature if that would help.
