Terminal.Gui: A Cross Platform Terminal UI Toolkit for .NET
Looking at the demo images, I must admit that I have some traumatic memories associated with that shade of blue on a console :) Mostly from fiddling with BIOS settings etc.My only experience with C# is in using the Unity 3D game engine. Now with a console apps ecosystem, cross-platform focus, GUI libraries, machine learning stuff, mobile apps. It's becoming an attractive prospect by the day.
