Managed Extensions for C++ or just Managed C++ is Microsoft's set of deviations from C++, including grammatical and syntactic extensions, keywords and attributes, to bring the C++ syntax and language to the .NET Framework. Managed C++ is not a complete standalone, or fully fledged programming language. These extensions allow C++ code to be targeted to the Common Language Runtime (CLR) in the form of managed code as well as continue to interoperate with native code.
