The 'Find Code Issues' option can find unused private methods. Is there an option even if a workaround or a hack to find unused public or protected methods? I understand these methods can be consumed by external clients and that's why R# doesn't look for them.
In my case all my clients are my own and I have the source. If I can get a list of these methods, I can then inspect them by other means and find out if they are truly unused. Some of these methods might have the wrong visibilty declaration. For example a public method should really be private as it's intended to be used in the same class only but the developer incorrectly made it public.
