gives information about turning on devpath, but how to you set this variable? Unfortunately it's not very clear on how you can set it. Is it set for all referenced dlls once set? Or can you set per dll?
I have also read that http://www.reflector.net/ offers a tool for GAC management. Most information I found on Devpath is linked with this tool.
Thanks
