Protip: If you rebuild and still experience weirdness (you shouldn’t have this often) – especially when working within a SCM (i.e. Perforce, git, etc.) directory it can sometimes be worth your while to delete the project VS solution, Binaries, Saved and Intermediate directories, regenerate the project solution and rebuild the project. This ensures that you have no out of date files which can rarely produce wonky results, especially if your SCM is misconfigured and is trying to prevent changes to these temporary files.
