Nice! So, with a little help from Particle folks, I learned that the next step after installing was to use the MSCode Command Palette (Ctrl-Shift P) to invoke, “particle: create new project”
Once I brought in some code that runs on the Photon, I used the Build menu to kick off a build. It builds. Rah.
This will be great particularly when I break the network stack and the web IDE isn’t available for an update (…without device reset).
Looking forward to more walkthroughs from you
