I have a general framework project which is referenced by many solutions. Whenever there is an update to a component which I would like to upgrade to, I normally right-click on the solution > Manage NuGet packages for solution > upgrade component for all projects. The problem is that for all other solutions, their projects (except from the common referenced one) is not updated to the latest one. If I try to do the same, it will not let me click on 'Update' to update all projects, as it detects that one project is already using the latest version. I have some other 4 or 5 projects in most solutions, and it is quite a headache to update them manually. Any ideas about it? I am using the latest version of NuGet and VS2012.
