NUnit by: Charlie Poole Rob Prouse

NUnit is a unit-testing framework for all .NET languages. It can run on macOS, Linux and Windows operating systems. NUnit can be used for a wide range of testing, from unit testing with TDD to full-fledged system and integration testing. It is a non-opinionated, broad and deep framework with multiple different ways to assert that your code behaves as expected. Many aspects of NUnit can be extended to suit your specific purposes. The latest version, version 4, is an upgrade from the groundbreaking NUnit 3 framework. It is a modernized version, aimed at taking advantage of the latest .NET features and C# language constructs. If you are upgrading from NUnit 3, be aware of the breaking changes (https://docs.nunit.org/articles/nunit/release-notes/breaking-changes.html#nunit-40). Please see the NUnit 4 Migration Guide (https://docs.nunit.org/articles/nunit/release-notes/Nunit4.0-MigrationGuide.html) and take care to prepare your NUnit 3 code before you do the upgrade. Supported platforms: - .NET Framework 4.6.2+ - .NET 6.0+ - .NET 8.0+

NUnit.Analyzers by: NUnit

This package includes analyzers and code fixes for test projects using NUnit 3+. The analyzers will mark wrong usages when writing tests, and the code fixes can be used to used to correct these usages. They will also aid in the transition from NUnit 3 to NUnit 4. Version 3.0 and upwards works in Visual Studio 2019 (version 16.3) or newer and also enables supression of compiler errors such as errors arising from nullable reference types. For Visual Studio 2017 one must use versions below 3.0 - note that these versions are no longer updated, so version 2.10.0 is the last version that works in Visual Studio 2017.

NUnit3TestAdapter by: Charlie Poole Terje Sandstrom

The NUnit3 TestAdapter for Visual Studio, all versions from 2012 and onwards, and DotNet (incl. .Net core). Note that this package ONLY contains the adapter, not the NUnit framework. For VS 2017 and forward, you should add this package to every test project in your solution. (Earlier versions only require a single adapter package per solution.)

OneOf by: Harry McIntyre

F# style discriminated unions for C#, using a custom type OneOf<T0, ... Tn> which holds a single value and has a .Match(...) method on it for exhaustive matching. Simple but powerful.

OpenCvSharp4 by: shimat

OpenCV wrapper for .NET. Since this package includes only core managed libraries, another package of native bindings for your OS is required (OpenCvSharp4.runtime.*).

OpenCvSharp4.runtime.win by: shimat

Internal implementation package for OpenCvSharp to work on Windows.

OpenCvSharp4.Windows by: shimat

OpenCV 4.x wrapper. All-in-one package for Windows users.

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

PCLCrypto by: Andrew Arnott

PCL Crypto provides a consistent, portable set of crypto APIs for .NET 4.5, Windows Phone 8.0 SL & 8.1 Xaml, 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.
