From the "Binary was not built with debug information." it seems that your binary was build in "Release" configuration. You have at least two options here:

i) build the binary in the "Debug" configuration

ii) change the project settings so that a Program Database file (PDB) is generated in the release configuration (check for example this). The PDB file should reside in the same directory as your EXE and with it you should be able also to debug your application.
