Nullable by: Manuel Römer

A source code only package which allows you to use .NET's new nullable attributes in older target frameworks like .NET Standard 2.0 or the "old" .NET Framework. This package does not contain any compiled binaries, but instead adds the attribute classes as C# source code to your project. Because this code is compiled together with the rest of your code, the built binaries will not have a dependency on this package, meaning that you can perfectly use it for both libraries and applications. The C# code is only included if you are targeting a framework version which does not support the new nullable attributes. For example, if you create a library which multi-targets .NET Standard 2.0 and 2.1, the majority of the attributes are not included in the .NET Standard 2.1 version, because it already provides these by default. Please see https://github.com/manuelroemer/Nullable for additional information on how to use this package.

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+
