My experience is that if the interface for the COM object does not change, everything runs fine after a rebuild and no reinstall is necessary. However, if the interface changes (add/delete Public methods or properties), then the component needs to be deleted and reinstalled. This makes some sense I suppose - MTS needs to know the interface to handle requests properly.

>It seems my COM component doesn't run in MTS after I update the component that was previously installed in MTS. Thus, I have to delete the component in the MTS package and reinstall it whenever I update the components. Is this a normal way of updating components running in MTS or am I missing something obvious? I'm not regenerating the component ID so...
