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
This worked for me in VS2017(My VS is in german so the tab names could be a bit different):
Project -> Properties -> C/C++ -> Code Generation -> RunTimeErrorCheck->\RTC
Also try deactivating the optimization option since making your code faster could mean not being able to watch the values of your local variables:
Project -> Properties -> C/C++ -> Optimization -> Disabled
