OpenIddict
Versatile OpenID Connect stack for ASP.NET Core and Microsoft.Owin
OpenIddict aims at providing a versatile solution to implement OpenID Connect client, server and token validation support in any ASP.NET Core 2.1 (and higher) application. ASP.NET 4.6.1 (and higher) applications are also fully supported thanks to a native Microsoft.Owin 4.2 integration. Developers looking for a simple and turnkey solution are strongly encouraged to use OrchardCore and its OpenID module, which is based on OpenIddict, comes with sensible defaults and offers a built-in management GUI to easily register OpenID client applications. Unlike many other identity providers, OpenIddict is not a turnkey solution but a framework that requires writing custom code to be operational (typically, at least an authorization controller), making it a poor candidate for the certification program. While a reference implementation could be submitted as-is, this wouldn't guarantee that implementations deployed by OpenIddict users would be standard-compliant. -

SmartEnum
A base class for creating strongly typed enum replacements in C#
SmartEnum is a .NET library that provides a strongly typed alternative to traditional C# enums by allowing developers to create richer, object-oriented enumeration classes. Instead of being limited to primitive numeric values, SmartEnum enables enums to include behavior, validation, and additional properties while preserving type safety and readability. The library is widely used in domain-driven design scenarios where business concepts require more expressive modeling than standard enums allow. Developers define custom enumerations by inheriting from a base SmartEnum class and declaring static instances, which can then be queried by name or value. The project also includes ecosystem support for serialization, Entity Framework persistence, and validation attributes, making it suitable for real-world enterprise applications. Overall, SmartEnum helps teams write more maintainable and intention-revealing domain code by replacing brittle primitive enums with extensible types. -

Testcontainers
A library to support tests with throwaway instances of Docker
Testcontainers is a Java library that supports JUnit tests, providing lightweight, throwaway instances of common databases, Selenium web browsers, or anything else that can run in a Docker container. Use a containerized instance of a MySQL, PostgreSQL or Oracle database to test your data access layer code for complete compatibility, but without requiring complex setup on developers' machines and safe in the knowledge that your tests will always start with a known DB state. Any other database type that can be containerized can also be used. For running your application in a short-lived test mode with dependencies, such as databases, message queues or web servers. Use containerized web browsers, compatible with Selenium, for conducting automated UI tests. Each test can get a fresh instance of the browser, with no browser state, plugin variations or automated browser upgrades to worry about. And you get a video recording of each test session, or just each session where tests failed. -

Xamarin.iOS & Xamarin.Mac
Bridges the worlds of .NET with the native APIs of macOS, iOS, tvOS
Bridges the worlds of .NET with the native APIs of macOS, iOS, tvOS, and watchOS. This module is the main repository for both Xamarin.iOS and Xamarin.Mac. These SDKs allow us to create native iOS, tvOS, watchOS and macOS applications using the same UI controls we would in Objective-C and Xcode, except with the flexibility and elegance of a modern language (C#), the power of the .NET Base Class Library (BCL), and two first-class IDEs—Visual Studio for Mac and Visual Studio—at our fingertips. This repository is where we do development for the Xamarin.iOS and Xamarin.Mac SDKs. The preferred method for installing Xamarin.iOS and Mac is to use the Visual Studio installers (Windows, Mac). The team also strongly recommends using the latest Xamarin SDK and Xcode whenever possible. -

YamlDotNet
YamlDotNet is a .NET library for YAML
YamlDotNet provides low-level parsing and emitting of YAML as well as a high-level object model similar to XmlDocument. A serialization library is also included that allows to read and write objects from and to YAML streams. YAML, which stands for "YAML Ain't Markup Language", is described as "a human-friendly data serialization standard for all programming languages". Like XML, it allows to represent of any kind of data in a portable, platform-independent format. Unlike XML, it is "human friendly", which means that it is easy for a human to read or produce a valid YAML document. The library has now been successfully used in multiple projects and is considered fairly stable. The library is compatible with mono's Ahead-of-Time compilation (AOT), and should work correctly on platforms that depend on it, such as Unity. -

ASP.NET API Versioning
Libraries which add service API versioning to ASP.NET Web API
ASP.NET API versioning gives you a powerful, but easy-to-use method for adding API versioning semantics to your new and existing REST services built with ASP.NET. The API versioning extensions define simple metadata attributes and conventions that you use to describe which API versions are implemented by your services. You don't need to learn any new routing concepts or change the way you implement your services in ASP.NET today. The default API versioning configuration is compliant with the versioning semantics outlined by the Microsoft REST Guidelines. There are also a number of customization and extension points available to support transitioning services that may not have supported API versioning in the past or supported API versioning with semantics that are different from the Microsoft REST versioning guidelines. -

CacheManager
CacheManager is an open source caching abstraction layer for .NET
CacheManager is an open source caching framework for .NET written in C# and is available via NuGet. It supports various cache providers and implements many advanced features. A simple but very efficient implementation. This handle is faster than any other in most scenarios and works cross-platform. Two implementations are available, based on System.Runtime.Caching and based on the new Microsoft.Extensions.Caching.Memory package. Redis can be used as an extremely fast and reliable out-of-process (or distributed) solution. Another great distributed solution is memcached, which can be used as a layer. The Redis implementation is based on the popular StackExchange.Redis package. Couchbase is primarily a document database but can also be used for simple caching. ASP.NET comes with its own in-process memory cache which can be used as one layer. Our Web NuGet package also comes with a custom OutputCacheProvider. -

CodeBehind Framework
CodeBehind is a modern back-end framework under ASP.NET Core.
CodeBehind is a modern back-end framework under ASP.NET Core. CodeBehind was developed by Elanat in 2023 and competes with Microsoft's default web frameworks (ASP.NET Core MVC and Razor Pages and Blazor). CodeBehind is an engineering masterpiece that simultaneously provides the possibility of development based on MVC, Model-View, Controller-View, only View, and Web-Forms. The type of structure and naming in CodeBehind is nostalgia and reminds me of former Microsoft Web-Forms. The aspx extension is the files of the view section in the CodeBehind framework and they support standard syntax (<%=Standard%>) and Razor syntax (@Razor). This framework guarantees the separation of server-side codes from the design part (HTML) and there is no need to write server-side codes in the view. -

CommandLineUtils
Command line parsing and utilities for .NET
CommandLineUtils is a library that helps developers implement command line applications in .NET. The primary goal of the library is to assist with parsing command line arguments and executing the correct commands related to those arguments. The library also provides various other utilities such as input helpers. This project helps you create command line applications using .NET. It simplifies parsing arguments provided on the command line, validating user inputs, and generating help text. CommandLineApplication is the main entry point for most console apps parsing. There are two primary ways to use this API, using the builder pattern and attributes. The library also includes other utilities for interaction with the console. A common scenario for options is to allow specifying a value-less option multiple times without value. The library supports counting flags by using bool[] or by checking for the number of values in Values.
