If you have been wondering what the thinking is behind the CX extensions to Microsoft's Visual C++, then we have a Q&A session video with Marian Luparu, a member of the design team.

CX are the extensions that have been added to C++ to allow it to work with WinRT. These extensions look a lot like the ones added to allow C++ to work with managed code, but don't get confused - they are different. They serve the same sort of purpose in that they create references to objects created in ways that are more complicated than heap objects.

Be warned, this video is an hour long and it is a bit slow to start. It also needs Silverlight.

If you can't see this video, try viewing it at Channel 9.
