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.

OpenTelemetry.Api by: OpenTelemetry authors

OpenTelemetry .NET instrumentation API

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 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.
