managed code Code that runs under the common language runtime. The common language runtime handles many tasks that would formerly have been handled in the application s executable. Managed code solves the Windows programming problems of component registration and versioning (sometimes called DLL Hell) because managed code contains all the versioning and type information that the common language runtime needs to run the application. The common language runtime handles registration dynamically at run time rather than statically through the system registry, as is done with applications based on the Component Object Model (COM).

metadata Data about data. For example, the name, version, security information, and size of a file constitute metadata about the file.
