Your Code is set to Optimize. In this mode, the compiler does code
optimizations any can sometimes not be able to debug.
Solution is to disable Optimizations while debugging.
1) Open the project properites from the Solution Explorer by right
clicking and selecting Properties
2) The Project Properties Dialog is shown.
3) Select your configuration from the Configuration Drop Down Box.
4) Under Configuration Properties select Build.
5) Set the Optimize Code drop down to False.
6) Rebuild and then debug.
