Open Source C# Frameworks

Powershell is a cross-platform, task-based command-line shell and scripting language that helps rapidly automate tasks that manage operating systems (Linux, macOS and Windows) and processes. It works well with existing tools and is optimized for dealing with structured data, REST APIs and object models. PowerShell was developed by Microsoft as a task management and configuration management framework. Powershell is designed to let you manage computers from the command line and improve the command-line and scripting environment.

File system/directory monitoring utilities with loggin and task processing support (can execute files or make a WCF service call). Multiple configuration options. Source code libraries can be used to create a custom file system monitor.

taskt (formerly sharpRPA) is the first truly free, easy-to-use, and open-source process automation client built on the .NET Framework in C#. taskt allows you to build and design process automation without needing to write application code. taskt allows you to automate the boring stuff and create efficienies by giving you the power to craft a digital workforce that executes and performs rule-based automation. No API? No Problem! Included is a "what you see is what you get" bot designer with dozens of automation commands. An element recorder and screen recorder is also included that can record and replay scripted automation. taskt works by allowing a bot developer to design a bot configuration known as a script. The bot configuration is then intepreted by a script engine at run-time and executes against the bot developer's selected parameter inputs. Each command contains the definitions for the required inputs as well as the required logic at run-time.

IKVM.NET is a JVM for the Microsoft .NET Framework and Mono. It can both dynamically run Java classes and can be used to convert Java jars into .NET assemblies. It also includes a port of the OpenJDK class libraries to .NET.

The DotNetWikiBot Framework was developed so that it can offer a helping hand with many complicated and routine tasks of wiki site development and maintenance. DotNetWikiBot Framework is a cross-platform full-featured client API, that allows you to build programs and web robots easily to manage information on MediaWiki-powered sites. DotNetWikiBot Framework can also be used for learning C# and .NET.

A software toolkit for using the EPCglobal Low Level Reader Protocol (LLRP) to communicate with conforming RFID readers.

If you are .NET developer and have a good idea for TC plugin - provided interface is the right choice for you. You can concentrate on the main functionality of your plugin withouth having to worry about most of mundane tasks of TC plugin building. Main features: - use flexibility and power of .NET Framework to create new plugin, - base classes for all TC plugin types - FS, Lister, Packer, and Content, - easy debugging with included tracing system, - all optional methods not implemented in managed plugin are excluded from the final TC plugin, - TC calls are translated into managed calls with parameters marshaling, - each plugin loads into separate Application Domain (AD) to provide isolation and security boundaries for executing managed code, - unified loader located in Default AD loads all types of TC plugins, - control over the lifetime policy for managed plugin instance, - auto support for Unicode and 64-bit features, - compact final binary files (usually < 100 KB)

An operating system kernel written in C# with a strong focus on security, reliability, and maintainability.

DotNetOpenServer SDK is an open source lightweight fully extendable TCP socket client/server application framework enabling developers to create highly efficient, fast, secure and robust cloud based smart mobile device and desktop applications. Why? Unlike most application server frameworks, which are implemented over slow inefficient stateless protocols such as HTTP, REST and SOAP that use bulky ASCII data formats such as JSON and XML, DotNetOpenServer has been built from the ground up with highly efficient stateful binary protocols.

This application was first designed to allow the creation of XML files based on .Net assemblies. But the developer (me) was out of time and there are some good XML free tools (like Eclipse) that can read XSD files, and allow you to create good XML files.

This project intends to modelize a framework for remote controlled airplanes. This framework includes PPM/PCM drivers and data telemetry (location, speed, altitude) based on the SensorsAPI, to provide a reliable augmented reality for FPV flights

AdvancedSendandReceive is a well featured SonicMQ client application implemented in C# for Sending and Receiving of JMS messages. It was inspired by the work done for BasicSendandReceive C# sonicmq

Af-Arch is an Open Source N-tier framework to build distribuited applications. Its license schema allows Open Source and commercial (closed source) applications. This is the foundation to build an new set of applications in a fast and reliable way.

Alchemi is a .NET grid computing framework that allows you to painlessly aggregate the computing power of intranet and Internet-connected machines into a virtual supercomputer (computational grid) and to develop applications to run on the grid.

Bedrock Framework is a set of low-level .NET networking APIs for building high-performance custom servers and clients. Its architecture focuses on transport-agnostic communication so protocols are not tightly coupled to a specific network mechanism. Builder APIs provide structured ways to configure client and server pipelines. The core package includes middleware and transports for sockets and in-memory communication. A separate experimental package contains protocol and transport implementations that may eventually move into the main framework. The project builds on connection abstractions introduced in ASP.NET Core for client-server communication. It is primarily intended for developers creating specialized networking stacks where performance, protocol control, and composability matter.

Brahma is an open-source library written for the .NET 3.5 framework (in C# 3.0), to provide high-level access to parallel streaming computations on a variety of processors, including GPUs.

The Cell framework is a scalable server framework written in C#. It's original purpose is for MMOG emulation but can be easily adapted to other areas. The project includes a proof of concept rewrite of the DAoC emulator DOL.

DiagApplications is an application and libraries to implement communications and data exchange between several .net application on the same computer or the same network.

Etch is a cross-platform, language- and transport-independent framework for building and consuming network services. With Etch, service development and consumption becomes no more difficult than library development and consumption.

FMACJ is a parallelization framework for the .NET CLR that gives your applications multicore/cluster support by saying what should be parallelized via attributes. You do not have to think about threads and networks at all. FMACJ also runs on Mono.

IdentityServer is a free, open-source OpenID Connect and OAuth 2.0 framework for ASP.NET Core. Founded and maintained by Dominick Baier and Brock Allen, IdentityServer4 incorporates all the protocol implementations and extensibility points needed to integrate token-based authentication, single-sign-on and API access control in your applications. IdentityServer4 is officially certified by the OpenID Foundation and thus spec-compliant and interoperable. It is part of the .NET Foundation and operates under their code of conduct. It is licensed under Apache 2 (an OSI-approved license). Active development happens on the main branch. This always contains the latest version. Each (pre-) release is tagged with the corresponding version. The aspnetcore1 and aspnetcore2 branches contain the latest versions of the older ASP.NET Core based versions.
