I just moved from Visual Studio 2008 to Visual Studio 2010 (final) and noticed one major flaw:
When I try to use AutoComplete in a C++ source file for managed C++, a small note in the footer appears:
IntelliSense for C++/CLI is not available
Uh, has IntelliSense for C++/CLI been dropped from Visual Studio 2010? Is there any way to get this back? It is rather useful...
