I\'m using Visual Studio 2015 preview, and I\'m trying to debug my project. I was using VS 2012 previously, and depended largely on being able to hover over and expand local
I found that simply changing the combobox with "Release and debug" back to debug allowed me to see the expansion of variables when debugging my code again.
This newest solution worked for VS 2017 on my home PC.
My work PC was able to show this expansion in 2017 after I did the "Build >> Clean Solution option and will even work when the combobox is set to "Release".
Best of luck to anyone else that wants this wonderful debugging help form VS. I hope that by using one of these methods you're able to get back to "normal".
