I've just released version 1.0 of my Resharper plugin, Agent Ralph.
Agent Ralph is a C# code clone detection and repair tool. If any two methods in the same class and file are functionally equivalent (ignoring comments, whitespace, and variable names) Agent Ralph will detect the situation and offer a quick fix to replace the body of one method with a call to the other.
You can read more and download Agent Ralph here.
I would love to hear from anyone using it, and any feedback, bug reports, or feature requests you may have as well.
