Intellisense in vs2010 with c++

Question

I can\'t get intellisense to work. Even if I start with an empty project and add just one file to it with only an include for iostream and an int main()

Answer 1

I know this is an old question, but I had a similar problem IntelliSense: 'No additional information available' (See 'Troubleshooting IntelliSense in C++ Projects' for further help.). My problem wasn't related with stdafx.h.

To solve my problem, I closed VS2010, deleted the .sdf and .suo files as well as the ipch directory inside the project's main folder.

Then I restarted VS2010, waited for it to build all its metadata again and Intellisense (autocompletion) worked nicely.

EDIT: I am not aware if this "maneuver" has negative side effects.
