managed code definition 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.
