This may not be what you are referring too BUT I can say as a .Net developer it's amazing how little .Net devs know about how the low level dev related stuff works because visual studio holds there hand.

I have blown people's minds by showing them how to just call msbuild or git from the command line etc... I think it's changing since dotnet core took over in that space but had a good 10 year run where generally no one at various work places had any understanding of what visual studio was really doing and it did bite us in the ass at times.
