Breakpoint will not currently be hit. No executable code associated with this line

I would suggest you firstly Delete the output files : Physically delete all generated DLLs, PDBs and EXEs. Then compile (rebuild) again to generate the files. Sometimes Visual Studio can "get lost" and "forget" to overwrite the output files when you build your solution.

This can happen for a few other reasons:

• The code the debugger is using is different from the code that the application is running
• The pdb file that the debugger is using is different from the code that the application is running
• The code the application is running has been optimized and debug information has been stripped out.
• The code in which you have breakpoints on hasn't been loaded into the process yet

I wound up having this issue too, the context of my app was a main app in C# which used unmanaged C++ code in a lower layer that I wanted to step into from the debugger. From the C# project properties I went into the Debug tab and under the Enable Debuggers section checked the "Enable unmanaged code debugging".

Wanted to mention that I experienced the "Breakpoint will not be hit..." error when porting some of my older MFC (managed--using clr support) projects into VS2015.

What fixed the issue for me was setting this:

Configuration Properties\Linker\Debugging\Debuggable Assembly

... to this:

Yes (/ASSEMBLYDEBUG)
