Когда я открываю проект, появляется сообщение об ошибке
"
Subversion detected a working copy that needs an explicit upgrade in 'some directory'.
While this working copy is not upgraded all files in this working copy will appear as new.
When a working copy is upgraded it can no longer be used by Subversion clients that weren't designed for this (or later) working copy formats.
Further working copy upgraded required warnings are suppressed until after you restart Visual Studio."
Как решить эту проблему. Я использую визуальную студию 2012, последнюю версию subversion и последнюю версию ankh.
