Windows Phone Apps
A few months ago, I created the FLC Live iOS app, using Adobe PhoneGap Build. Then, using some of that knowledge, I created a hybrid HTML5/C# Windows Phone app for the Faith Life Church Daily Bible Reading program. In the process of all this, I started working with APIs (and more specifically with REST and JSON). Now, I've cut my teeth on a fully-native C# (well, more XAML than C#) FLC Live Windows Phone app to watch the Faith Life Church live internet services.
