I've been searching on this exception, and one thing they suggest is that if the same assembly is loaded from 2 different locations, that can cause grief - and indeed it is.
When Outlook opens, it seems to load the addin from C:\Documents and Settings\deanc\Local Settings\Application Data\assembly\dl3\KDBRMV9Y.9BV\X4AEVA3M.YJY\53b145d6\294be7c3_1ee8c601\, but the COM control loads from a different location. Anyone know the reason for the load from Local Settings? Is that a VSTO design time trick, or is it going to do that on clients anyway (which probably means I will never be able to remote from the Addin/COM control combination).

There is a possibility that the files are loading from 2 different locations (the Outlook Addin loads from the Addin project Release folder, whereas the COM control loads from the UI projects Release folder - if that makes a difference?). They are both compiled in the same solution though. Dino -----Original Message----- From: Discussion of advanced .NET topics.

Before I posted the code I did, I'd scratched out a simple app that setup 2 appdomains, both of which connected to the same remote server. Then I read the email trail a bit closer and got the impression you were just trying to talk from one app domain to another. I'm not near that code at the moment, but if you email me offlist I can send it your way. Alternatively, maybe include the actual exception details you're seeing? -Mike 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 DevelopMentor(r) http://www.develop.com View archives and manage your subscription(s) at http://discuss.develop.com =================================== This list is hosted by DevelopMentor® http://www.develop.com View archives and manage your subscription(s) at http://discuss.develop.com
