What is a Managed Code

Managed code runs inside the environment of CLR i.e. .NET runtime. In short all IL are managed
code. But if you are using some third party software example VB6 or VC++ component they are
unmanaged code as .NET runtime (CLR) does not have control over the source code execution
of the language.
