Novità nel Class Designer per sviluppatori C++ in Orcas
Sono poche... ma meglio che niente...
TheMarch CTP of Visual Studio 2007will 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.
