Introducing Callisto, a toolkit of sorts for XAML Metro style apps. When starting my own app building for the Consumer Preview, I realized there were some experiences and common things that I wanted to implement that weren’t existing controls in a way that I could easily re-use my efforts across app to app that I was building. The foundation building blocks in the platform were there of course, as was a few existing Open Source projects that I could leverage (yay Open Source!). I refactored the combination of these things into a single toolkit that I’ve been using for my apps.
