What is linux mono?

A cross-platform .NET operating environment developed by Xamarin.

Mono is a free and open source project hosted by Xamarin (previously Novell, first Ximian). The goal of this project is to create a set of .NET tools that match the ECMA standards (Ecma-334 and Ecma-335), including a C# compiler and a common language framework. Unlike Microsoft's .NET Framework (common language running platform), the Mono project can not only run on Windows systems, but also on Linux, FreeBSD, Unix, OS X and Solaris, and even some game platforms, such as: Playstation 3, Wii Or XBox 360.

Background:

Mono is a project hosted by Novell (initiated by Xamarin) and led by Miguel de lcaza, an open source project dedicated to pioneering the use of .NET on Linux . It contains a C# language compiler, a CLR runtime, and a set of class libraries, and implements ADO NET and ASP NET. It enables developers to develop programs in Linux using C#. The goal of this project is to create a series of .Net tools that comply with standards ECMA (Ecma-334 and Ecma-335), including a C# compiler and a common language (CL (Common Language) execution platform (Platform). With Microsoft's .Net Differently, the Mono project can not only run on Windows systems, but also on Linux, FreeBSD, Unix, Mac OS X and Solaris.

Mono is now dual-licensed by Novell, which is similar to the situation of Qt and Mozilla application suites. Mono's C# compiler and related tools are released under the GNU General Public License (GPL). The runtime library is released under the GNU Lesser General Public License (LGPL), and its class library is released under the MIT License. These are open source licenses, so Mono is an open source software. If you plan to contribute your source code to Mono, you A copyright assignment must be signed to Novell to allow it to relicense the code under other agreements, thereby allowing Novell to retain its dual-licensing ability to hold Mono's commercial agreement.

Microsoft has developed a .NET implementation called Shared Source Common Language Infrastructure (Shared Source CLI) that can be used for FreeBSD, Windows, and Mac OS X. Microsoft's Shared Source Agreement does not It is not an open source software agreement, and may not be enough for the community (it explicitly prohibits commercial use of the software). We can also see another .NET implementation version, the Portable NET project, which has many similarities with the Mono project Same target.

The Mono virtual machine contains a just-in-time compilation engine that is available for the following processors: x86, SPARC, PowerPC, ARM, S390 (32-bit mode and 64-bit mode), x86-x64, IA64 and SPARC in 64-bit mode. This virtual machine can compile the code in real time or pre-compile it to native code. For those systems not listed, a code interpreter is used.
