So, with a full disclaimer that I am somewhat newish to C# and have only learned it because it operates in game engines faster (currently) and has become the language du'jour for game programming.
The glaring hole with C# however is, it is designed for Visual Studios, and that is NOT available for Linux. This is a GIANT hole in the programming world. Visual Studios Code fills that gap, thankfully, and I can use it in engines like Godot to make games. While these may not be AAA titles, they aren't an insignificant portion of developers in the world. Not only that, but C# is used in other areas of development where the preferred platform is Linux.
Luckily, for me and those of my ilk, people have hobbled together a system in VSC where Linux works with Godot and the exports are fine, but it's not nearly as easy as a supported system like Visual Studios on Windows and Mac.
