Mike, I get an InvalidCastException:
System.InvalidCastException: Return argument has an invalid type. at System.Runtime.Remoting.Proxies.RealProxy.ValidateReturnArg(Object arg, Type paramType) at System.Runtime.Remoting.Proxies.RealProxy.PropagateOutParameters(IMessag e msg, Object[] outArgs, Object returnValue) at System.Runtime.Remoting.Proxies.RealProxy.HandleReturnMessage(IMessage reqMsg, IMessage retMsg) at System.Runtime.Remoting.Proxies.RealProxy.PrivateInvoke(MessageData& msgData, Int32 type) at Xception.Midas.DataAccess.Generated.ClassFactory.NewInstance() at Xception.Midas.DataAccess.Generated.ClassFactory.CreateInstance() in C:\Documents and Settings\deanc\My Documents\Visual Studio 2005\Projects\Xception\Midas\DataAccess\Generated\ClassFactory.cs:line 1311 But I don't get that error from the first AppDomain. 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® http://www.develop.com View archives and manage your subscription(s) at http://discuss.develop.com
