OpenTK by: Team OpenTK

The Open Toolkit is set of fast, low-level C# bindings for OpenGL, OpenGL ES, OpenAL and OpenCL. It runs on all major platforms and powers hundreds of apps, games and scientific research. It provides bindings for GLFW windowing, input and a game loop, and is the perfect start for your own game engine. OpenTK comes with simple and easy to follow tutorials for learning *modern* OpenGL. These are written by the community and represent all of the best practices to get you started. Learn how to use OpenTK here: https://opentk.net/learn/index.html Sample projects that accompany the tutorial can be found here: https://github.com/opentk/LearnOpenTK We have a very active discord server, if you need help, want to help, or are just curious, come join us! https://discord.gg/6HqD48s

OpenTracing by: The OpenTracing Authors

This library is a .NET implementation of the OpenTracing API. To fully understand this platform API, it's helpful to be familiar with the OpenTracing project and terminology more generally. For the time being, mild backwards-incompatible changes may be made without changing the major version number. As OpenTracing and opentracing-csharp mature, backwards compatibility will become more of a priority.

PCLCrypto by: Andrew Arnott

PCL Crypto provides a consistent, portable set of crypto APIs for .NET 4.5, Windows Store, Xamarin.iOS, Xamarin.Android. This makes it easier to create cross-platform .NET libraries and apps. Crypto functionality includes asymmetric and symmetric encryption and signatures, and key derivation. PCLCrypto calls into each native platform's crypto API for maximum performance. For RSA operations this produces a 2-100X improvement in performance on Android and iOS over using the standard RSACryptoServiceProvider API.
