Getting a users Facebook profile after Authenticating your Xamarin app with Azure

I've recently been looking at the authentication offered by Azure for use in a mobile app, specifically using social auth providers like Facebook to allow a user to sign up for my app. The auth setup is incredibly easy, with Azure taking care of a lot of the hard stuff. There are also loads of great docs on how to get it set up - including the Micr…

Device.StartTimer and iOS backgrounding

I recently completed a lecture on backgrounding in iOS and Android as part of the Xamarin University. During this lecture, one topic of discussion came up with no real answer - how Device.StartTimer() in Xamarin.Forms affects backgrounding. With iOS, if you enable backgrounding using BeginBackgroundTask(), you have 3 minutes to stop all backgroun…

Some of these are understandable as they are different on each platform so it's hard to provide a consistent experience for the developer. Some are bad ommisions as they are vital to all platforms.

iOS pull to refresh without using a UITableView

I've been working on the UI for my current app, trying to make some usability improvements. The main screen is a list of data containing an image and some text. Although this is a standard UI pattern, the problem I'm having with it is one of size. List rows are usually short and full width. For text this is fine, but not so good for images, the…

Setting the font for an Entry control using Xamarin.Forms

Xamarin.Forms depsite being very cool is stil a bit lacking when it comes to not only a good range of controls, but also to the abilities of those controls. One example of this is the Entry control - a simple text box. One thing you can't do with the out of the box implementation is to set the Font. Such a normal thing to do, but not supported. L…

Grouping in ListViews with Xamarin.Forms

Xamarin.Forms provides a lot of cool features to use for mobile app development, and the documentation is pretty good - but sometimes the cool features you want to use are a bit lacking in docs. There are example projects but it can be hard to interpret what you need to do to get something working. The latest area that was confusing me was groupin…
