[dexter-vs] DirectoryNotFoundException when clicking in the error list

[AndreasSummer]

If you double click on an entry in the error list, then an error message appears: An exception has been encountered. This may be caused by an extension.

In the VS ActivityLog you will find an entry:
System.IO.DirectoryNotFoundException: Das System kann den angegebenen Pfad nicht finden.
