For the specific example given I have turned down many individuals who sound like they have a similar background because they could not figure out how to work outside of their toolchain. I see it all the time with .NET and Java developers, if they are not in Visual Studios or Eclipse they don't know how to even compile their software. Both those ecosystems are fantastic and developers can be very productive, especial…
That said I haven't really observed this phenomenon among any of my coworkers who run on Visual Studio and Windows full time. I think experienced devs who care about their craft enough to know a modicum of computer science understand what is happening "under the hood" when tooling like Visual Studio abstracts build steps away from them, or at least enough to be able to manually replicate it themselves if needed.
