It doesn't work (ctrl+shift+space). (Or else it's working and I need a picture of what it's supposed to look like.)
There is only a tip box saying "use smart completion to show all" but that's it. The tip box blocks my keyboard typing, so I am getting negative productivity since I have to hit escape all the time to get rid of it.
On this page, in the "In Object Intializers" section, I don't get the intellisense box you show.
