Top 23 C# Game development Projects

  • MonoGame

    One framework for creating powerful cross-platform games.

  • Project mention: The MonoGame Foundation launch | /r/monogame | 2023-11-15

    To highlight this shift, we are introducing a new website which is now fully automated with Github. The paint is still fresh, but we hope to expand it with more information about the MonoGame Foundation, like how it operates, and how to join it or contribute.

  • Entitas

    Entitas is a super fast Entity Component System (ECS) Framework specifically made for C# and Unity

  • Project mention: Entitas VS Friflo.Json.Fliox - a user suggested alternative | libhunt.com/r/Entitas | 2024-01-30
  • WorkOS

    The modern identity platform for B2B SaaS. The APIs are flexible and easy-to-use, supporting authentication, user identity, and complex enterprise features like SSO and SCIM provisioning.

  • Project mention: Unity Software plans to reduce its workforce by 25%, eliminating ~1,800 jobs | news.ycombinator.com | 2024-01-10

    In general it took me less time to rewrite the code-base then implementing some of the workarounds for missing features in Unity (e.g. HTTP2) in the first place.

  • FlaxEngine

    Flax Engine – multi-platform 3D game engine

  • Project mention: Not only Unity... | /r/opensourcegames | 2023-11-11

    Flax (MIT/C++) https://github.com/FlaxEngine/FlaxEngine

  • Silk.NET

    The high-speed OpenGL, OpenCL, OpenAL, OpenXR, GLFW, SDL, Vulkan, Assimp, WebGPU, and DirectX bindings library your mother warned you about.

  • Project mention: Is there a real time graphics llibrary in c# | /r/csharp | 2023-05-17

    A couple other options than what has been suggested so far: - TerraFX.Interop.Windows. Raw, blittable, 1:1 bindings for all Win32, D2D/D3D11/D3D12 APIs (there's also a version with Vulkan bindings). As close to doing #include as you can get in C#. This is my personal favorite, I use it in my own ComputeSharp library, and transitively we use it in the Microsoft Store too 🙂 - Silk.NET another version of high-performance bindings, more opinionated than TerraFX and with some additional helpers to make it a bit easier to use.

  • 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.

  • Project mention: Unhandled SEHException when running OpenTK project - What am I doing wrong? | /r/opengl | 2023-06-25

    Open a new issue on Github. Include all of this, and provide info on your OS and GPU.

  • UnrealCLR

    Unreal Engine .NET 6 integration

  • Project mention: Since you're asking yes u can use C# in unreal | /r/Unity3D | 2023-09-18
  • InfluxDB

    Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.

  • Veldrid

    A low-level, portable graphics library for .NET.

  • Project mention: Is there a real time graphics llibrary in c# | /r/csharp | 2023-05-17

    I'd recommend Veldrid

  • YarnSpinner

    Yarn Spinner is a tool for building interactive dialogue in games!

  • Project mention: Dialogue system with scriptable objects | /r/Unity3D | 2023-05-30

    Another option if you don't want to implement it yourself though is to use an already built library. I've been playing with YarnSpinner a little bit recently and I'm liking it so far. I can't give much more details than that, but it's maybe worth a look. At least for some reference.

  • MyBox

    MyBox is a set of attributes, tools and extensions for Unity

  • Duality

  • Project mention: Does it still make sense to roll your own ECS? | /r/gameenginedevs | 2023-07-31

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