Commented Unassigned: Manage nuget for solution does not correctly show the new packages [3373]

I have notice that when we work in a team if one of my colleague update the package on his side and publish the changes to our vcs, then if I downlload this update the visual studio manager will keep offering me to update the same packages again and again. I have notice that if I remove the old package from my disk(packages directory) then the Package manager stop offering. It seems that the list of possible update is link to what I have on disk and not what are my real dependencies.
Comments: Here is what I did User A: Create project install jquery 1.8 check in UserB checkout update jquery to 2.0 checkin User A get latest changes go to manager nuget for solution no updates are listed on the installed tab it correctly shows jquery 2.0.3
