    ProxyKit

    ProxyKit

    A toolkit to create code-first HTTP reverse proxies on ASP.NET Core

    A toolkit to create code-first HTTP Reverse Proxies hosted in ASP.NET Core as middleware. This allows focused code-first proxies that can be embedded in existing ASP.NET Core applications or deployed as a standalone server. Deployable anywhere ASP.NET Core is deployable such as Windows, Linux, Containers and Serverless (with caveats). Having built proxies many times before, I felt it is time to make a package. Forked from ASP.NET labs, it has been heavily modified with a different API, to facilitate a wider variety of proxying scenarios (i.e. routing based on a JWT claim) and interception of the proxy requests/responses for customization of headers and (optionally) request/response bodies. It also uses HttpClientFactory internally that will mitigate against DNS caching issues making it suitable for microservice/container environments.

    RabbitMQ .NET Client

    RabbitMQ .NET Client

    RabbitMQ .NET client for .NET Standard 2.0+ and .NET 4.6.1+

    The RabbitMQ .NET client is an implementation of an AMQP 0-9-1 client library for C# (and, implicitly, other .NET languages). The library is open-source, and is dual-licensed under the the Apache License v2 and the Mozilla Public License v2.0. This means that the user can consider the library to be licensed under any of the licenses from the list above. For example, the user may choose the Apache Public License 2.0 and include this client into a commercial product. Codebases that are licensed under the GPLv2 may choose GPLv2, and so on. 6.x versions of the library require .NET 4.6.1 or a .NET Core version implementing .NET Standard 2.0. They also introduce potentially breaking public API changes covered in the changelog. 4.x and 5.x versions of the library require .NET 4.5.1 or later or .NET Core. For .NET Core users, 2.0 is the minimum supported version for 5.x series.

    RapidDevelop R#

    RapidDevelop is an IDE and Compiler for a new programming language!

    RapidDevelop R# is an IDE and Compiler for a programming language called RapidLang. RapidLang (or r#) is a programming language based on c# and .Net which introduces some new paradigms and shorthand to improve development times and to help ease the creation of software in general. Being an extension of C#, you can link, build or compile native C# assemblies or Classes and Libraries so that you can very easily port existing code. The programming language also exists in a managed shared library and can be dropped into any .net project so that you can use the compiler in your own projects, with plans to even provide executing compiled code in memory, effectively creating a RapidLang Scripting Language plugin!

    ReactiveUI

    ReactiveUI

    An advanced, composable, functional reactive model-view-viewmodel

    An advanced, composable, functional reactive model-view-viewmodel framework for all .NET platforms! Describe what you want, not how to do it & rejoice in the increased readability of your code. Code is communication between people, that also happens to run on a computer. If you optimise for reading by humans, then over a long time your project will end up better. Create re-usable chunks of functionality that can be seamlessly integrated into your reactive pipelines. These chunks might be widely applicable, or specific to your application. Regardless, you have the power to write and test code once, and leverage it many times over. Any device, any platform. Share business logic between your mobile and desktop applications. ReactiveUI has first class support for Xamarin Forms, Xamarin.iOS, Xamarin.Android, Xamarin.Mac, Tizen, Windows Forms, Windows Presentation Foundation (WPF), & Universal Windows Platform (UWP).
