Resharper 6 highligts a lot of resources.GetString("...") statements with the error "Can not resolve Symbol" but the resource entry exists in the resx file.
picture 1 shows the error, picture 2 show the resource entry (pictures are attached to the bug report)
What I found out so far is, that the error is shown when the english resx file (en.resx) does not contain this string. However our primary/neutral language is german.
Adding [assembly: NeutralResourcesLanguageAttribute("de")] to the AssemblyInfo.cs has not helped.
I have create a bug report http://youtrack.jetbrains.net/issue/RSRP-215013?projectKey=RSRP and because I have several thousand error I just wanted to make sure you notice this problem sooner than later. ;)
