Go To Definition: "Cannot navigate to the symbol under the caret."

I got the same problem. I did all those steps mentioned in all above comments. It didn't work. But when I closed Visual Studio, deleted ".vs" folder (in the solution folder) then reopened Visual Studio. It now works like a charm. The problem is gone.

The last couple of days I've been getting this error, at least twice a day.. really annoying! None of the solutions proposed here has worked for me. What I found, and since it was pretty difficult to find I'm writing it down here, was to:

• Close Visual
• Open Console and navigate to Visual installation folder, in my computer is C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE
• run devenv.exe /resetuserdata
• Open Visual Studio, it's going to take some time to load.

Disclaimer: I'm using Xamarin

TAKE INTO CONSIDERATION WHAT @OzSolomon and @xCasper HAVE SAID:

@OzSolomon

Know that this will reset many of your IDE customization, including installed plugins.

Make sure you're comfortable with that before using /resetuserdata

@xCasper

If you have your settings synced through Microsoft, however, most of the preferences seem to restore themselves. I say most because it seems my keybindings did not restore and are back to being default. Everything else, such as my selected theme and colorization choices, the layout of my IDE (where I have tabs for instance), and what not seem to of come back.
