I recently created a monodevelop solution using the Assets/Sync MonoDevelop project. When I open it in monodevelop, I can see the solution and classes in my Classes pane, but when I try to do a “Find in Files” it tells me “Currently there is no open solution.”
I’ve had this problem forever too. Did anyone find a…well… ‘solution’?
EDIT…Actually alexfoo’s answer worked for me. Funny as I’ve had this issue for ages and I thought I’d already tried that. May have been some changes with the unity updates.
