问题
Is there any way to do this at any level other than disabling intellisense in all of Visual Studio? Just wanted to confirm/deny a suspicion about its performance in some of our overly giant projects/solutions while keeping it in other areas that we actually care about.
回答1:
AFAIK there's no way to selectively disable Intellisense. Try disabling it completely and see if that would make a big difference.
回答2:
I have noticed a slow down in Visual Studio on my work machine with several VS extensions installed like Spell Checker. Disabling them helped.
