Luckily, for the project of this type, you can use SkiaSharp (which is awesome) or simply implement a rendering back-end that targets OpenGL/Vulkan/DX/Metal. There are rich binding libraries with low/zero overhead to do so like TerraFX or Silk.NET or you can just do it directly.

For example, Avalonia implemented Vulkan back-end some time ago, no C or C++ required: https://github.com/AvaloniaUI/Avalonia/pull/12737

Even then, you are absolutely not married to any of these GUI frameworks, but if are targeting desktop, then Avalonia offers great user experience.
