It would be very useful if the VisualGDB Project Properties dialog offered not only “Release” and “Debug” but also “All Configurations.” This would make setting directories and preprocessor values much quicker and less prone to mistakes.
Unfortunately this is currently not possible as VisualGDB uses rich GUI to present various settings (e.g. command lists) and merging settings from different configurations there would greatly overcomplicate the design. The only workaround we could offer is to programmatically edit the .vgdbsettings files.
Yes, I can understand that, it is unfortunate and has already led me to spend alot of time looking for problems when the issue was a simple option being incorrect in one of the configurations.
