I am using Visual Studio Ultimate 2012 its intelliSence is good for mini projects but for complex line of code or having hundreds of errors then its intelliSence becomes very poor after correcting an error intelliSence still points it as an error for next 1 to 2 minutes. even some times intelliSence points an error while there exists no error at all. If I reopen the project then that error has gone.
intelliSence of Xcode is much more fast and reliable then Visual Studio 2012. So Please make it as much better as you can
