Managed code unmanaged code

Managed code)

Code executed by the Common Language Runtime Library environment (rather than directly by the operating system. Hosted code applications can obtain the Common Language Runtime library service, such as automatic garbage collection, Runtime Library type check, and security support. These services help provide unified managed code application behavior independent of platform and language.

Unmanaged code-unmanaged code

Code that is directly executed by the operating system outside the public Language Runtime Library environment. The unmanaged code must provide its own services such as garbage collection, type check, and security support. Unlike the hosted code, the latter obtains these services from the public Language Runtime Library.
