After adding an image to this project, while Xcode is closed, I got this exception:

System.IO.DirectoryNotFoundException: Directory '/Users/jackson/Projects/edictate/edictate/eDictate3/obj/Xcode/6' not found.

Followed by this exception:

I added a Directory.Exists() before requesting a dir listing which should prevent the first exception, but not sure how it's happening in the first place (I mean, I doubt you rm -rf'd /Users/jackson/Projects/edictate/edictate/eDictate3/obj/Xcode/6 yourself)
Comment 2 Jeffrey Stedfast 2012-01-27 16:43:37 UTC
I think I figured out how the second exception happened (MD got into an inconsistent state due to the first exception).

Added a try-finally around XcodeSyncChanges() so that won't happen.
