Charles, I believe that to do what you want you need to use the "Application Root Directory" entry on the properties dialog of your COM+ app. I seem to remember that you can point your COM+ app to a specific folder and from this you can have your app use a specific version of the Framework. I've never done this but I seem to remember reading about it in doing some other research for COM+ settings.
Hope this helps, Nick -----Original Message----- From: Discussion of advanced .NET topics.

Not quite. You can't load different versions into the same process. But different processes can host different versions of the CLR no problem. You don't need separate machines for that. In the case of a COM+ server app running in its own instance of dllhost.exe, this means you should be able to configure different COM+ apps to use different versions of the CLR. I just don't have any experience in this specific (COM+) area that would help the OP... -Mike Bear Canyon Consulting LLC http://www.bearcanyon.com http://www.pluralsight.com/mike =================================== This list is hosted by DevelopMentor(r) http://www.develop.com View archives and manage your subscription(s) at http://discuss.develop.com =================================== This list is hosted by DevelopMentorĀ® http://www.develop.com View archives and manage your subscription(s) at http://discuss.develop.com
