This release performs much better with large projects (no more rebuilding IntelliSense every time the IDE starts), widens support for inline error checking, and rebuilds much of the interface to make those marathon coding sessions a little more pleasant.
Visual Studio 2010 released
My only problem with VC++ 2010 is it takes twice as long to load the project, but the new error system makes up for it. (Shows possible errors before compile). So helpful =D
