I have Resharper 4.5 build 188.8.131.528.2 installed with Visual Studio 2008 SP1. I've noticed recently that there are two sets of Resharper settings files in my solution directories, one for 4.5 and one for 5.0:
Both files are identical:
I have made some changes to my Resharper 4.5 settings recently, but I have never installed Resharper 5.0. I changed my Code Style Sharing settings from "Not share, applies to all solutions opened by current user" to "Not shared, per solution, stored in a file". I did this because I have multiple solutions that contain some of the same projects.
Why do I have 5.0 settings when I don't have Resharper 5.0 installed?
