Very nice extension. After Microsoft have been removed the macros in Visual Studio 2012, I was bored to don't have this feature. When you have a big solution with many projects, it help to don't have to wait before the entire process even if your firsts projects failed.
I was having this problem in VS2013. I fixed it by searching ("Quick Launch" in the upper right hand corner) for "Stop On First Build Error." Then I toggled both the options from False to True. After that, the options appeared in my Build menu, and didn't disappear when I unchecked them.
I installed on a VS 2013 Ultimate edition and it does not work. It kept compiling after the first error. I thought it was suppose to stop. (And yes I do have the Stop on First error selected in the build menu).
Doesn't it stop at all? Also, despite the name it doesn't stop immediately on first error, it stops after the first project has failed, i.e. it doesn't try to build additional projects after one has failed. Does it try to build all projects for you, even with the "Stop on first build error" option checked?
@Michael: Sorry, I don't have VS2012 anymore to test on. I built it with VS2013 and it insisted on updating the project. I don't think the Visual Studio Gallery allows you to download older versions. Probably the only thing you can do is get the source code and build it yourself against the VS2012 extension kit.
