Answer 1

I've had the same problem this morning. Installing Visual Studio 2013 wasn't an option for me (And I very much doubt it would be for lots of people). Rebooting has usually solved the problem before, (and a bit less drastic),

Manually attaching the process (TOOLS -> Attach to process (ctrl + ALT +p)) to w3wp.exe for IIS, or IIsExpress.exe also worked, which leads me to suspect that VS is having trouble figuring out which process it should attach to automatically.
