I'm having problems with intellisense not showing up for std::shared_ptr. A quick search uncovered some old issues being resolved for boost::shared_ptr, but I haven't seen anything on the new std version.
case=56278 is marked as fixed internally which means it have to go through additional testing but there is a good chance that this problem will be fixed in the next build. It may solve your problem as well since it seems to be the same problem.
