'Action' type disappearing from Solution - Intellisense spits the dummy


i've had happen couple of times different sl4 solutions, , i'm absolutely stumped might be.

the problem is: when use action delegate type, visual studio starts complaining there needs using statement added though

  using system;

is present.  has not a problem action<t>, non-generic version.  intellisense, builds fine, have intellisense warnings on show saying it's unknown type.

i'm stumped.  far know, action is basic part of of mscorlib, , that's referenced, , nothing's been changed regards taht.  has else seen quirk?

now i've seen happen on more 1 solution thought i'd ask.  everyone!

hi,

   havn't seen this. happen follow sort of patten?

   mean if you things in particular order happens.

best regards
