I\'ve read every StackOverflow that I could find on this issue, but I still can\'t work it out.
I\'m trying to deploy an app to actual device (NOT emulator)
I got that error for a really simple reason...just opened a new solution I downloaded from GitHub, pressed F5, and got it!
I had left my build configuration in the default "Debug - ARM" setting, when I changed to "Debug - x64" it worked fine!
(Just adding another reason for completeness, not likely to affect your case!)
