some are working some are not working.
for example,
i did
using System.Web.Security;
MembershipUser myObject = Membership.GetUser();
I'm using VS2005, but, I found that, in order convince it to build intellisense for boost, I had to specify the explicit path to the boost includes - shades of 1988! A relative path did not work. Dunno how this is going to affect the team, might try the environment variable trick to see if that's a workaround this poor indexing implementation.
