Yeah, it's a beta, but I'm using C2 to publish very small apps for now. Considering that I only use VS to edit a couple things and publish, a 6 GB minimum install + all the "bloat" they add to a PC it's a lot.
I'm trying to and make VS "15" work now ASAP. It seems that the latest version, Preview 4, already works, so now it's time to find out exactly what packages do we need.
I hope we get fixes (Windows Store plugin) along this Xbox fad soon, because right now microtransactions don't work.
