Project Description
Designed to bring Code Refactoring capabilities to the F# Language in Visual Studio 2010.

"Code refactoring is the process of changing a computer program's source code without modifying its external functional behavior in order to improve some of the nonfunctional attributes of the software. Advantages include improved code readability and reduced complexity to improve the maintainability of the source code, as well as a more expressive internal architecture or object model to improve extensibility." source: Wikipedia
