what is DLL Hell and how it is solved in .NET?

Answer Posted / kamlakar singh

DLL Hell refers to the set of problems caused when multiple applications attempt to share a common component like a dynamic-link library (DLL) or a Component Object Model (COM) class. In the most typical case, one application will install a new version of the shared component that is not backward compatible with the version already on the machine. Although the application that has just been installed works fine, existing applications that depended on a previous version of the shared component might no longer work. In some cases, the cause of the problem is even more subtle.
