MonoDevelop

MonoDevelop (also known as Xamarin Studio) is a discontinued open-source integrated development environment for Linux, macOS, and Windows. Its primary focus is development of projects that use Mono and .NET Framework. MonoDevelop integrates features similar to those of NetBeans and Microsoft Visual Studio, such as automatic code completion, source control, a graphical user interface (GUI), and Web designer. MonoDevelop integrates a Gtk# GUI designer called Stetic. It supports Boo, C, C++, C#, CIL, D, F#, Java, Oxygene, Vala, JavaScript, TypeScript, and Visual Basic.NET. Although there is no word from the developers that it has been discontinued, nonetheless, it hasn't been updated in 4 years and is no longer installable on major operating systems, such as Ubuntu 22.04 and above. MonoDevelop can be used on Linux, macOS, and Windows. Officially supported Linux distributions include CentOS, Debian, Fedora, openSUSE, SUSE Linux Enterprise, Red Hat Enterprise Linux, and Ubuntu, with many other distributions providing their own unofficial builds of MonoDevelop in their repositories. macOS and Windows have been officially supported since version 2.2. MonoDevelop has included a C# compiler (an alternative to MSBuild and CSC) since its earliest versions. It currently includes a compiler that supports C# 1.0, C# 2.0, C# 3.0, C# 4.0, C# 5.0, and C# 6.0. A customized version of MonoDevelop formerly shipped with Windows and Mac versions of Unity, the game engine by Unity Technologies. It enabled advanced C# scripting, which was used to compile cross-platform video games by the Unity compiler. It has since been replaced by Visual Studio Community, except on Linux versions.
