When working with applications built using compilers from Microsoft you must ensure that your application is built with debugging information.
Debugging information must be enabled for debug builds (enabled by default) and for release builds (disabled by default).
To enable debugging information for a DLL/EXE, open the project settings/solution for that DLL/EXE, select the build type (debug or release), then modify the settings for the compiler to enabled debugging information and the settings for the linker to enable debugging information. You must enable both settings to generate debugging information.
