This document discusses two horror stories involving NuGet package management. The first story describes an issue where uninstalling one package that transformed a web.config file removed an element that another still-installed package required. This could cause errors. The second story indicates the described issue has now been fixed. The document seeks ideas on how to address conflicts when multiple packages transform the same configuration file during install and uninstall.
