I am unable to add an existing project or an existing item to any project or solution in visual studio 2008 (SP1). I only get an "Operation cannot be completed error".
Things I have tried that did not work:
- ran devenv /resetsettings (no luck)
- Un-installed Resharper 4.5. (no luck)
- Repaired Visual Studio from Add/Remove Programs. (no luck)
- Un-installed AnkhSVN. (no luck)
Note I am using Windows 7.
