Yeah, it is called Managed C++ in .NET 1.x, C++/CLI starting in .NET 2.0 
and C++/CX in WinRT.

Managed C++ and C++/CLI can be JITed or compiled to machine code via 
NGEN. They make use of .NET GC for ref data types. There is a standard 
defined for C++/CLI, ECMA-372.

C++/CX compiles to native code, while making use of COM reference 
counting, the usual first level of GC algorithms.
