The cool thing about Universal Windows Platform (UWP) apps is that they run on an assortment of devices, from PCs, tablets, and phones to (soon) Xboxes and HoloLens, among others.

API Convergence Gets Real in Windows 10

Last year, I wrote a universal app named Pic Me (later renamed to “Picture Me”) for Windows 8.1 and Windows Phone 8.1. The main reason I wrote it was that my daughter said “wouldn’t it be cool to have an app that shows you all the photos you’ve been tagged in on Facebook, and that…

Supercharging Xamarin Forms with Custom Renderers, Part 3

One of the limitations of Xamarin Forms that frequently pains developers is the fact that the Label control supports text wrapping and text truncation, but it doesn’t support both at the same time. Specifically, Label’s LineBreakMode property can be set to LineBreakMode.WrapText to wrap text, or it can be set to LineBreakMode.TailTruncation to replace text…

Supercharging Xamarin Forms with Custom Renderers, Part 1

Xamarin Forms includes an assortment of “views,” more commonly known as controls, to help you build cross-platform UIs using XAML. Each control has a default appearance, and each control exposes properties that allow you to customize its appearance. But what if you’re handed a set of UI requirements that can’t be achieved using those properties?…
