In a single solution, if I have the same source file present in multiple projects (with different project settings, e.g. different #defines), Intellisense and all the features depending on it seems to arbitrary pick one of the project settings when I edit the source file.
How do I get Intellisense to switch which project settings it uses for that file ?
If that is not possible, it would be at least useful to know which project Intellisense picks ?
