IronRuby is a version of the Ruby programming language developed for Microsoft Common Language Runtime (CLR), which is part of the .NET framework. IronRuby has been released under the Microsoft Permissive License.
The original Ruby is an open source, interpreted, object-oriented programming (OOP) language similar to Smalltalk, Perl or Python. Ruby was created by Yukihiro Matsumoto, who chose the gemstone's name to suggest "a jewel of a language," elegant but powerful. Ruby users and programmers can easily remove, redefine or build on parts of the code.Proponents of IronRuby claim that it improves on the original language by using lightweight code generation, resulting in faster runtime performance than interpreted code. IronRuby can run through Silverlight and on the Windows Desktop and Windows Server operating systems ( OSs).
