Open Source C# Frameworks for Linux

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.

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.

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.

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.

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

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

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.

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.

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.

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.

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.

Intel® Mobile Platform SDK 1.3 covered by BSD license, enables developers to build mobile-aware applications. It provides a set of libraries and runtime components, and programming interface, common across Windows and Linux platforms.

JPPF makes it easy to parallelize computationally intensive tasks and execute them on a Grid.

The JProgress project provides tools for connectivity with Java clients and the Progress database. JProgress provides an n-tier software architecture for database access for executing remote requests over WANs and the Internet.

Task scheduling service written completely in managed C#. The service can be linked into other projects (DLL) or installed as a stand-alone Windows service (EXE), and is able of executing tasks written in any .NET language.

PHPRPC is a Remote Procedure Calling (RPC) protocol that works over the Internet. It is secure and fast. It has a smaller overhead. It is powerful and easy to use. This project is the client and server implementations of the PHPRPC.

Servers Development Kit (SrvDK) is an open source library, written in C#, for quick creation of effective and robust multi-client TCP servers. NOTE: This is work in progress, so far the application is NOT yet usable!

A light-weight component model and services framework providing enterprise quality services.

Smart Thread Pool is a rich thread pool implemented in pure .net and can run on Windows, WindowsCE, Silverlight, ASP.NET, and Mono.

Web Objects in XML (Framework) is an interoperable and lightweight system for distributed objects. It is currently built in Java and C#. Remote objects are serialized in a standard XML format, and they are accessible trough their own URL.

PHP5-based platform. Additional support for Java/C# is to be expected later on.
