c# - Visual Studio 2012 "the project file has been moved, renamed, or is not on your computer" -
i'd been working on visual studio project, , decided rename it. after little bit of renaming, under new name. tried open project in visual studio, , load failed, saying project file had been moved, renamed, or deleted. can edit project via c# project file among other class files, no matter how try rename files change back, load still fails.
any ideas on how fix this?
