I added some sample projects using Veldrid and OpenTK.OpenAL here: https://github.com/bcarruthers/garnet/tree/master/samples
One makes use of ECS in a real-time simulation and the other is turn-based with idiomatic F# code and no ECS. There's also wrapper code over Veldrid to help with sprites and tiling.
They come to about 37 MB when publishing standalone trimmed.
