While Jack Zhai-MSFT's solution worked I still had some weird behavior: breakpoints were working partially. Found solution here that works perfectly: Breakpoint Failed to Bind - Visual Studio 2015 While the above link is loaded with tons of solutions in my case changing configuration from Release to Debug under Build menu Configuration Manager solved all my breakpoints related problems.
