C++ support added to Class Designer in VS 2007 March CTP
The March CTP of Visual Studio 2007 will have support for C++ projects in Class Designer. This will be limited only to visualizing your existing code from native C++ projects.
Editing code from Class Diagrams and Managed C++ projects will not be supported in the Orcas release due to time/resource constraints.
Cheers,
Ramesh Rajagopal.
Class Designer Team.
