Unable to compile program

I guess your issue is due this:

but I'm not familiar at all with VS and Particle Workbench
Here's some kind similar issue and a lot of info in one place, how to deal with Particle Workbench.

Particle Workbench New user question

I am new to software and just getting started on Particle using Relay Shield. I used the Web IDE successfully, now moving to the Particle Workbench on the desktop (need the serial debug). When I create a new project, copy the code from the example code, it’s giving a compile error. build.mk:65: *** “No sources found in c:/Sunder/projects/Particle IO/junk2/Trial/”. Stop. make[2]: *** […/…/…/build/recurse.mk:12: user] Error 2 make[1]: *** […/build/recurse.mk:12: modules/photon/user-part] Error…

Hope this will help
