Unity version: 5.5.1 OS: Windows 10 I cannot put some breakpoints in Visual Studio 2015 to debug my Unity project. It seems to allow breakpoints 50% of the time, but it happens consistently across unity projects. I don't have this problem with other types of VS projects. Visual Studio tools for Unity is installed. Things I have tried: * Reinstalling Unity, VS and VSTU * Running as administrator * Re-creating a project by scratch (deleting folder + re-importing all the assets) * Deleting the Library folder * Deleting project settings * Changing advanced build settings "debug info" from "pdb only" to "full" ...should I just give up?
