C++/CX (Component Extensions) is a language extension for C++ compilers from Microsoft that enables C++ programmers to write programs for the new Windows Runtime platform, or WinRT. It brings a set of syntax and library abstractions that interface with the COM-based WinRT programming model in a way that is natural to native C++-programmers.
The ref new instead returns a handle, which is a reference to the object rather than the pointer itself. These references are counted so that the object can be automatically deleted when there are no longer any references to it.
