SharpOS is a discontinued computer operating system based on the .NET Framework and related programming language C#. [1] It was developed by a group of volunteers and presided over by a team of six project administrators: Mircea-Cristian Racasan, Bruce Markham, Johann MacDonagh, Sander van Rossen, Jae Hyun, and William Lahti. [4] It is no longer in active development, and resources have been moved to the MOSA project. As of 2017, SharpOS is one of three C#-based operating systems released under a free and open-source software license. [5] [6] SharpOS has only one public version available [2] and a basic command-line interface.

History

SharpOS began in November 2006 [7] as a public discussion on the Mono development mailing list as a thread named Operating System in C#. After attracting many participants, Michael Schurter created the SharpOS.org wiki and mailing list to continue the discussion at a more relevant location. Soon after, the core developers (Bruce Markham, William Lahti, Sander van Rossen, and Mircea-Cristian Racasan) decided that they would design their own ahead-of-time (AOT) compiler to allow the operating system to run its boot sequence without using another programming language. Once the AOT compiler was far enough developed, the team then started to code the kernel. This was met with long periods of inactivity and few active developers due to lack of interest in unsafe kernel programming. [8] On 1 January 2008, the SharpOS team made their first milestone release public, [2] this is the first version of the software to appear in the SharpOS SourceForge package repository available for general public use.

GNU Free software project

GNU is an extensive collection of free software, which can be used as an operating system or can be used in parts with other operating systems. The use of the completed GNU tools led to the family of operating systems popularly known as Linux. Most of GNU is licensed under the GNU Project's own General Public License (GPL).

FreeDOS is a free operating system for IBM PC compatible computers. It intends to provide a complete MS-DOS-compatible environment for running legacy software and supporting embedded systems.

BitKeeper is a software tool for distributed revision control of computer source code. Originally proprietary software, it was released as open-source software under the Apache License 2.0 on 9 May 2016.

BitKeeper is no longer developed.

GNU Project Free software project

The GNU Project is a free software, mass collaboration project that Richard Stallman announced on September 27, 1983. Its goal is to give computer users freedom and control in their use of their computers and computing devices by collaboratively developing and publishing software that gives everyone the rights to freely run the software, copy and distribute it, study it, and modify it. GNU software grants these rights in its license.

ReactOS Free software Windows NT-like operating system

ReactOS is a free and open-source operating system for amd64/i686 personal computers intended to be binary-compatible with computer programs and device drivers made for Windows Server 2003 and later versions of Windows. ReactOS has been noted as a potential open-source drop-in replacement for Windows and for its information on undocumented Windows APIs.

GNU/Linux naming controversy Issues of what to call a system with the GNU toolchain and the Linux kernel

Within the free software and the open-source software communities there is controversy over whether to refer to computer operating systems that use a combination of GNU software and the Linux kernel as "GNU/Linux" or "Linux" systems.

Inferno (operating system)

Inferno is a distributed operating system started at Bell Labs and now developed and maintained by Vita Nuova Holdings as free software under the MIT license. Inferno was based on the experience gained with Plan 9 from Bell Labs, and the further research of Bell Labs into operating systems, languages, on-the-fly compilers, graphics, security, networking and portability. The name of the operating system and many of its associated programs, as well as that of the current company, were inspired by Dante Alighieri's Divine Comedy. In Italian, Inferno means "hell" — of which there are nine circles in Dante's Divine Comedy.

Cooperative Linux Software to run both Windows and Linux

Cooperative Linux, abbreviated as coLinux, is software which allows Microsoft Windows and the Linux kernel to run simultaneously in parallel on the same machine.

The Common Development and Distribution License (CDDL) is a free and open-source software license, produced by Sun Microsystems, based on the Mozilla Public License (MPL). Files licensed under the CDDL can be combined with files licensed under other licenses, whether open source or proprietary. In 2005 the Open Source Initiative approved the license. The Free Software Foundation (FSF) considers it a free software license, but one which is incompatible with the GNU General Public License (GPL).

Singularity (operating system) Experimental operating system from Microsoft Research

Singularity is an experimental operating system (OS) which was built by Microsoft Research between 2003 and 2010. It was designed as a high dependability OS in which the kernel, device drivers, and application software were all written in managed code. Internal security uses type safety instead of hardware memory protection.

Linux Family of Unix-like operating systems

Linux is a family of open-source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991, by Linus Torvalds. Linux is typically packaged in a Linux distribution.

FreeBSD Free Unix-like operating system

FreeBSD is a free and open-source Unix-like operating system descended from the Berkeley Software Distribution (BSD), which was based on Research Unix. The first version of FreeBSD was released in 1993. In 2005, FreeBSD was the most popular open-source BSD operating system, accounting for more than three-quarters of all installed simply, permissively licensed BSD systems.

Linux began in 1991 as a personal project by Finnish student Linus Torvalds: to create a new free operating system kernel. The resulting Linux kernel has been marked by constant growth throughout its history. Since the initial release of its source code in 1991, it has grown from a small number of C files under a license prohibiting commercial distribution to the 4.15 version in 2018 with more than 23.3 million lines of source code, not counting comments, under the GNU General Public License v2.

Cosmos (operating system) Toolkit for building operating systems

C# Open Source Managed Operating System (Cosmos) is a toolkit for building operating systems, written mostly in the programming language C# and small amounts of a high level assembly language named X#. Cosmos is a backronym, in that the acronym was chosen before the meaning. It is open-source software released under a BSD license.

Linux-libre Version of the Linux kernel without binary blobs

Linux-libre is a modified version of the Linux kernel that contains no binary blobs, obfuscated code, or code under proprietary licenses. Binary blobs are software components with no available source code. In the Linux Kernel, they are mostly used for proprietary firmware images. While generally redistributable, binary blobs do not give the user the freedom to audit, modify or, consequently, redistribute their modified versions. The GNU Project attempts to keep Linux-libre in synchronization with the mainline Linux kernel.

NetBSD Open-source Unix-like operating system

NetBSD is a free and open-source Unix-like operating system based on the Berkeley Software Distribution (BSD). It was the first open-source BSD descendant officially released after 386BSD was forked. It continues to be actively developed and is available for many platforms, including servers, desktops, handheld devices, and embedded systems.

Mono (software) Computer software project

Mono is a free and open-source .NET Framework-compatible software framework. Originally by Ximian, it was later acquired by Novell, and is now being led by Xamarin, a subsidiary of Microsoft and the .NET Foundation. Mono can be run on many software systems.

Linux kernel-based operating systems have been widely adopted in a very wide range of uses. All the advantages and benefits of free and open-source software apply to the Linux kernel, and to most of the rest of the system software.
