RapidDevelop R# is an IDE and Compiler for a programming language called RapidLang. RapidLang (or r#) is a programming language based on c# and .Net which introduces some new paradigms and shorthand to improve development times and to help ease the creation of software in general. Being an extension of C#, you can link, build or compile native C# assemblies or Classes and Libraries so that you can very easily port existing code. The programming language also exists in a managed shared library and can be dropped into any .net project so that you can use the compiler in your own projects, with plans to even provide executing compiled code in memory, effectively creating a RapidLang Scripting Language plugin!
