It's a long time since I used Visual Studio's Intellisense, but while we're waiting for VS 2010 beta 2 support I noticed that VS2010's Intellisense may be better than R# in the following case:
type the following (or similar)
var perm = new PrincipalPermission(
now in VS 2010 if we type 'P' VS shows a list of items starting with P but highlights PermissionState, i.e. matching the argument type of one of the PrincipalPermission constructor overload.
In VS2008 with R# the same code, Intellisense shows a list of items starting with P but always highlights PrincipalPermission, which doesn't really make sense.
Am I missing something, or is this something R# could do better?
