Arch VS Svelto.ECS

For C#, I've found Arch, which looks pretty much like what I need. I would use it with MonoGame.

Arch is a high-performance c# entity component system for game dev and data-oriented programming. It offers incredible performance combined with a simple API. The best part is that it already has a big ecosystem with additional tools and even source generators to aid development!

Also a minimal example with monogame was added, which demonstrates some techniques and workflows.

A few weeks ago I developed a C# high performance ECS designed for game development and data oriented programming : Arch.

I also already added multithreading, inlined queries and a few other usefull features to it ^^ genaray/Arch: A high performance c# Archetype Entity Component System ( ECS ) with optional multithreading. (github.com)

Arch ECS

Hey everyone, i developed a little c# archetype based ecs in my freetime : Arch

For existing libraries (which you can either choose to use, or choose to reference to look at how they implement ideas), maybe you can take a look at the following. I don't have experience with them, so I don't know how well they are implemented nor whether they strictly adhere to data-oriented design practices to get maximum performance, but it's not always strictly necessary to get the best performance out of everything unless you are writing a 3d AAA game with hundreds of thousands or even millions of entities: * Svelto.ECS - A C# ECS * FLECS - Written in C, but it also has a C# binding and it's a pretty well-regarded ECS implementation * ENTT - "Modern C++" ECS implementation * Bevy - a full game engine with a robust ECS implementation, written in Rust and quite modern.
