Free C# Compilers and Interpreters
C# is an object-oriented programming language created by Microsoft. This page lists free C# compilers, interpreters and integrated development environments (IDEs) for writing C# computer programs.
If you prefer commercial C# compilers, you might want to check out Microsoft Visual Studio (Professional or Premium).
Free C# Compilers
- Microsoft Visual C# Express 2013
The free Microsoft Visual C# compiler included in the Visual Studio Express 2013 allows you to create programs for the .NET framework. It works on Windows Vista, 7, 8, Server 2008 R2 SP1 and Server 2012 (although not XP). It includes a subset of the full (commercial) Visual Studio. WARNING: this version of Visual Studio Express requires you to register for a Microsoft account, and associate your installation with this account, otherwise you will only be able to run the program for 30 days.
- Microsoft XNA Game Studio Express
Develop non-commercial games in C# for Windows with the Microsoft XNA Game Studio Express. You will also need to download the Microsoft Visual C# Express Edition (see elsewhere on this page for the link). The XNA Game Studio Express includes the XNA Framework, a set of managed code development libraries that supposedly speeds up your development of games on Windows, as well as the XNA Framework Content Pipeline, tools that help you add 3D content to your games. Also included are documentation, starter kits (for example, a SpaceWar starter kit is included), etc. Important note: although the website says the XNA Game Studio Express allows you to develop for the Xbox 360, you must pay an annual fee to develop games for the Xbox 360. In fact, from the FAQ on the site, it appears that you don't even get the XNA Framework for Xbox 360 in this Express edition. You should also read the End User License Agreement (EULA) carefully before you start developing (to find out what the other restrictions are). In case you're wondering, XNA stands for "XNA's Not Acronymed", following the tradition started by GNU's "GNU's Not Unix". Currently supported systems: Windows XP SP2 and Vista. (Note: Microsoft regularly changes the web addresses for its products, making it difficult for others to link to them. If you find that the above link does not work, please let me know.)
- The Mono C# Compiler
Mono is an open source cross-platform implementation of Microsoft's .NET Development Framework. It includes a C# compiler (generating .NET virtual machine code, not native code), a runtime for CLR (the Common Language Infrastructure) and a set of libraries. You can embed the runtime into your C# applications. Mono currently works on Linux (both x86 and PPC), Windows, S390, with work being carried on for Strong/ARM and SPARC.
- Microsoft Visual C# 2010 Express
The free Microsoft C# compiler creates programs for the .NET framework (including .NET Framework 4). It includes a subset of the features available in the full (commercial) Microsoft Visual Studio 2010.
