This was also the Visual SourceSafe days. How I do not miss that!
C# wiggled its way in eventually.
Back in 2008, I was pretty much using Emacs for most programming languages. The only exception was C# and Javascript.
As the years pass to now, I rarely use a programming language outside of emacs. I have enough years in my career to not tell me what I can and cannot do to get things done.
That was also the project where I tested if git reached the point where you can have "normal" people work with it as well (which worked pretty well). I never accepted any project where they'd have me work with idiotic proprietary source control, unless the project was "migrate away from that".
Since around 2014 -- It has been Git all the way.
Well, until recently. Codebase at my current job is all contained in a single Subversion repo. It is difficult to maintain and branching takes GBs!
One of my first goals is to move over to Git, and into smaller Git repos. Of course, I have Magit to get it done. :-)
I like how people think I am purposely being different or difficult because I do C# development in emacs. Many have never heard of it. If they have its from forums or youtube videos.
Think of their mindset -- Its not like I have moved away from Visual Studio to Visual Studio Code. I am using Emacs. They must think I am trying to be difficult or special.
I have also swapped my L-CTRL key with CAPS specially for improving my emacs experience.
Regardless, when we do pair programming (or something) on my screen and they watch me use Emacs on a C# project, they soon understand. :-)
