This question is a follow up to my question about sharing resources between web applications, because I have not yet found a good solution.
I have a web application
hey this is not the best way to do things but i used to do this in my asp.net 1.1 days - you can try this - shift your user controls into a seperate project, and publish this project as a virtual directory under iis
as long as you are not using codebehind - your updates would be cool (only update shared user control folder)
if you do use codebehinds - redeploy the user control dlls into different projects
once you are done with this - map these user controls into all projects using their virtual paths
