Debugger popup message "Getting DataTip text"

This solution works fine for me:

Uncheck the new langage JavasScript Language Service in Options -> Editor -> JavaScript -> Language Service.

Option capture


I'm having this same issue and there doesn't appear to be a solution. It's extremely frustrating because when the "Getting DataTip text..." does popup and eventually goes away, my breakpoints no longer work.

The solutions listed here have not solved the problem, I've tried them ALL ... even a wipe and re-install of OS and VS 2015.

Debugging without ability to do property evaluation and other implicit function calls is basically NOT debugging and defeats the purpose.

Microsoft seem to be aware of the problem but keep closing the tickets as "unable to replicate" ... yet, a simple Google Search will show many many thousands of hits of developers running into this problem. I keep opening tickets with Microsoft, but they just keep getting closed or merged with no solution.

Cheers, Rob.


The ONLY solution that worked for me:

  1. CMD window (Run As Admin)
  2. type SFC /SCANNOW and wait for it to complete and hopefully fix any errors
  3. Reboot
  4. Bring up VS 2015 or 2017 without loading any project
  5. In VS select Tools | Import and Export Settings | Reset all Setting ... now pick the template you use (i.e. VB, C, Web)
  6. Exit VS
  7. Load VS project and debug

Cheers, Rob.


(1)Tools->Options, uncheck the setting Debugging / General / Enable property evaluation and other implicit function call, and enable the Use Managed Compatibility Mode.

(2)Deleted all the .suo/obj/Bin/.user files in your project, and then re-open your project, clean and build your solution, debug it again.
