Managed code is a term widely used in the field of computer programming, particularly in relation to the .NET framework developed by Microsoft. This term refers to software that runs within a managed environment, where the execution and memory management are controlled by a runtime environment rather than being directly controlled by the operating system. Synonyms for managed code include "controlled code", "runtime-managed code", or simply "managed software". These synonymic expressions all convey the same underlying concept of software that benefits from features like automatic memory management, exception handling, and security provided by the .NET framework, resulting in safer and more efficient execution.
