2: Video Capture and Overlays
DirectDraw video capture is faster than running through Chrome. I’m using Aforge, which made it really easy to get that up and running. Then, when I learned more about WPF, I discovered I can do most of the same things (probably all, with more effort) that I did in Electron, such as overlays of scores, messages, etc.
3: Development Time
I still need to get peer-to-peer/webRTC working in C#, plus, figuring out a way to get two instances of development code running on the same computer (to test local-host connections before over a physical network).
