Unable to see values in debug mode when mouse placed over local variables VS 2015

Question

I am unable to see the values of local variables in debug mode when mouse pointer placed over them or by adding add watch option in visual studio 2015. I am also getting the error

Internal error in the expression evaluator

I have tried the following to fix the error

• Rebuilded the solution

• Restarted Visual studio

• Restarted My PC

• Set Debug - > Options -> Ticked Use Mange Compatibility mode

• Set Debug - > Options -> Ticked Use Native Compatibility mode

• Set Debug - > Options -> Use the legacy c# and vb expression evaluators (Note:When I enable this I can see that it works for some of the codes when debugging on a device, but not all.In the emulator it works for all the code, but in earlier version of visual studio (2013) it works both for emulator and device without setting anything in visual studio at all)

  None of these solved the problem. How can i fix this ?

Answer 1

Running the visual studio in Administrator mode seems to solve the issue also I need to put a tick mark on

Set Debug - > Options -> Use the legacy c# and vb expression evaluators

as well.

Answer 2

This can occur when the Optimize code option is checked in Project Properties>Build
