I am working on a project that has many websites(asp.net mvc3.0). We need to maintain same UI for all websites. So i created a class library and put content and script folder in that library as embedded resource. It is working fine for java script files but fails to download css class.Failed to load resource: the server responded with a status of 404 (Not Found) weburl/bin/Content/Site.css Please suggest some solution.Thanks,Nabin
