SDL2 + VS2015 debug : miscellaneous file?


I’ve been trying to follow the Handmade Hero videos, but with SDL2.
I’ve been writing my code in a text editor, and I want to debug in VS. However, with my SDL2-project, VS doesn’t show my source files. It only has a 'miscellaneous file.
With code from the HH project (no SDL2), debugging works fine in VS.

Any idea what I could be doing wrong ?
Thanks !
