managed code

managed code

   <operating system> Code that is executed by the {.NET} {common
   language runtime} (CLR).  {VB.NET} code is always managed code
   but {C++ .NET} can optionally use unmanaged code.  Managed
   code provides {metadata} allowing the CLR to manage security
   (role-based as well as new approaches to code access
   security).  The CLR also handles errors, manages the program
   {stack} and finds {methods} in assembly modules.  Managed data
   is memory that's subject to {garbage collection}.  There are
   additional restrictions to permit interoperability of
   different languages, for example, {Visual Basic} {arrays} must
   be zero-based.
