VS2010 “An item with the same key has already been added”
I recently installed Visual Studio 2010 and copied and converted an old VS2005 solution to VS2010 When I edit this solution, if I try to change a control's .image property, VS2010 creates a message box telling me that "An item with the same key has already been added" (screenshot below), and won't let me browse for an image. I can add images for any other solution, even others ported from VS2005, but not this one. Any idea what I'm doing wrong? An item with the same key has already been added. http://img121.imageshack.us/img121/3592/errorsy.jpg I worked this out thanks to a search. The
