I created that one some days ago. It is partially my fault: I changed
the regional settings for some test with my program and forgot to
restore them. Apparently Resharper uses the current locale to read in
the XML files. This now fails with my locale being different than when
the XML files were written. I had the same problem in my application and
solved it by surrounding the xml file reading/writing by a temporary
change of Thread.CurrentThread.CurrentCulture to the invariant culture.
