Sadly my final outcome was to use the GAC for about 6 components. Another complication I had to overcome was the remoting configuration - I use a customised compression sink based on Ingo Rammer's sample, but I cannot figure out how to configure that in code - so I have to ship a .config file, and then from code try to locate it and call it. Caused a bit of frustration.
Am looking at the GAC API to work out how to programmatically install my assemblies in the GAC when I auto-download a new version from the web. Obviously a simple solution is to shell to a batch file, but I'd rather do it cleanly if I can. Dino -----Original Message----- From: Discussion of advanced .NET topics.
