StopOnFirstBuildError is an extension that stops a solution build immediately if one project fails to build. There is a menu item in the Build menu that allows you to turn the functionality on and off, the menu item is only visible in multi-project solutions (since it would make no sense in a single project solution). More information is available at:
Version 1.2 notes: Gareth Lennox (https://github.com/garethl) contributed a patch so now you can select whether to show the error list or not after a cancelled build from the Build menu. You can also access the options from Tools->Options->Stop on First Build Error, and the options are remembered between runs.
