NGraphics

NGraphics is a cross platform library for rendering vector graphics on .NET. It provides a unified API for both immediate and retained mode graphics using high quality native renderers. (by praeclarum)

OpenTK

The Open Toolkit library is a fast, low-level C# wrapper for OpenGL, OpenAL & OpenCL. It also includes windowing, mouse, keyboard and joystick input and a robust and fast math library, giving you everything you need to write your own renderer or game engine. OpenTK can be used standalone or inside a GUI on Windows, Linux, Mac. (by opentk)

OpenTK is probably the most known library for that.

I used OpenTK, an OpenGL framework for C# and hacked together a small app that renders a fullscreen textured quad (in this case OP's image) with a shader I found in this article.

i'd go for OpenTK so you don't have to learn c++ in addition. also one of the most important things is understanding how to communicate with the GPU and for that https://learnopengl.com/ is a great resource. (also creating a 3d engine is not really that much harder than a 2d engine in my opinion)
I need something like Pygame + PyOpenGL or LWJGL, but for C#/.NET

But OpenTK can, and you can use it within godot if you add it as a C# library with godot C# https://opentk.net/

Thanks! I'm creating an engine (far from being ready for public use) while developing the game based on OpenTK which is pretty much like GLFW for C# (it is a bit more advanced than that though), so yeah pretty much from scratch.
