Roslynator
A collection of 500+ analyzers, refactorings and fixes for C#
A collection of 500+ analyzers, refactorings, and fixes for C#, powered by Roslyn. Roslynator client libraries are meant to be used for the development of your own analyzers/refactorings. It does not contain any analyzers/refactorings themselves. All analyzers in package Roslynator.Formatting.Analyzers are disabled by default. Roslynator Testing Framework can be used for unit testing of analyzers, refactorings and code fix. The framework is distributed as a NuGet package. Some analyzers require options to be set. For this purpose, there is special analyzer ROS0003 that report a diagnostic if an analyzer is enabled but the required option is not set. ROS0003 is disabled by default. If you want to configure Roslynator on a user-wide basis you have to use the Roslynator config file. The default configuration file can be used with an extension for Visual Studio or VS Code. -

SubsCheck-Win-GUI
A GUI program interface designed by SubsCheck for Windows users
SubsCheck-Win-GUI is a Windows-based graphical application written in C# (for the .NET platform) designed to help Windows users check and manage subscription links (for proxy nodes) easily via a GUI rather than CLI scripts. The application provides a user interface for loading subscription links or node lists, performing checks (e.g., reachability, latency), and presenting results in a user-friendly view. It also supports auto-update of version information and links to downloads, as evidenced in its release notes (version 2.0.1.7 optimizing update mechanism). The tool caters to those who may prefer a desktop environment rather than deploying and debugging worker scripts themselves; it fills the niche of “subscription manager” on Windows. Because it deals with subscription feeds (for proxies), it also indirectly supports workflows similar to the WorkerVless2sub project but focused on the client/desktop side rather than backend generation. -

YoutubeExplode
Abstraction layer over YouTube's internal API
YoutubeExplode is a .NET library that provides a high-level abstraction for interacting with YouTube data, enabling developers to retrieve metadata and download media streams programmatically. The project exposes a clean API that allows applications to query videos, playlists, channels, and search results without relying on the official YouTube Data API. Under the hood, the library parses raw page data and leverages reverse-engineered internal endpoints to obtain structured information and stream manifests. Developers can use it to access details such as titles, authors, durations, captions, and available media formats, as well as to download audio or video streams for further processing. The library is designed to be intuitive and cross-platform through .NET Standard compatibility, making it suitable for desktop tools, automation pipelines, and media utilities. -

Basic Computer Games
An updated version of the classic "Basic Computer Games" book
Basic Computer Games is a modern revitalization of the classic “Basic Computer Games” book’s collection of games, ported and expanded into various modern, memory-safe and scripting languages. It includes illustrative code examples of many classic games (e.g. Blackjack, Bowling) in multiple languages, with the goal of making the historical games accessible and educational in safe modern environments. Definitely use the most recent versions and features of the target language, but also try to keep the code samples simple and explainable – the goal is to teach programming in the target language, not necessarily demonstrate the cleverest one-line tricks, or big system "enterprise" coding techniques designed for thousands of lines of code. -

ClashN
A clash client for Windows, support Mihomo
clashN is a Windows desktop client for the Clash networking engine, providing a graphical interface to manage proxies, rules, and profiles. It wraps the Clash core in a familiar, configurable UI so users can import subscriptions, switch nodes, and observe connections without editing YAML by hand. The app emphasizes rule-based routing, letting you combine rule providers and policy groups to steer traffic by domain, process, or destination category. System-wide proxy control, including PAC and TUN/TAP options, helps route applications that don’t natively support proxies. Logs, traffic charts, and connection inspectors make troubleshooting and optimization straightforward. For power users, granular profile editing and hot-reloading reduce the friction of iterating on configurations. -

Confluent's .NET Client for Apache Kafka
Confluent's Apache Kafka .NET client
confluent-kafka-dotnet is Confluent's .NET client for Apache Kafka and the Confluent Platform. Confluent-kafka-dotnet is a lightweight wrapper around librdkafka, a finely tuned C client. There are a lot of details to get right when writing an Apache Kafka client. We get them right in one place (librdkafka) and leverage this work across all of our clients (also confluent-kafka-python and confluent-kafka-go). Confluent, founded by the creators of Kafka, is building a streaming platform with Apache Kafka at its core. It's high priority for us that client features keep pace with core Apache Kafka and components of the Confluent Platform. confluent-kafka-dotnet is derived from Andreas Heider's rdkafka-dotnet. We're fans of his work and were very happy to have been able to leverage rdkafka-dotnet as the basis of this client. -

Orleans
Orleans is a cross-platform framework for building distributed apps
Orleans builds on the developer productivity of .NET and brings it to the world of distributed applications, such as cloud services. Orleans scales from a single on-premises server to globally distributed, highly-available applications in the cloud. Orleans takes familiar concepts like objects, interfaces, async/await, and try/catch and extends them to multi-server environments. As such, it helps developers experienced with single-server applications transition to building resilient, scalable cloud services and other distributed applications. For this reason, Orleans has often been referred to as "Distributed .NET". It was created by Microsoft Research and introduced the Virtual Actor Model as a novel approach to building a new generation of distributed systems for the Cloud era. The core contribution of Orleans is its programming model which tames the complexity inherent to highly-parallel distributed systems without restricting capabilities or imposing onerous constraints. -
