Async programming in C# is something that's been covered in detail by a number of people (google Brandon Minnick or Filip Ekberg), but it's still something I see misused on a regular basis, so here is a very brief overview of a couple of traps to

A common scenario in apps is to want users to sign in before they get access to the features and functions of the app. In order to sign in, users must first register, may want to change their password, and at some stage some of them will forget their password

If you're using

Wow - it's been a long time since my last post. I've been very busy with something that I hope to chat about before too long... In the meantime, here are some thoughts on using the Xamarin.Forms SearchBar control with Mvvm. Firstly, there's

It was great fun speaking on Xamarin at TechEd last week. Thanks to all who were able to attend, and extra thanks to those who completed the evaluation and left some feedback. Special thanks also to the staff at White Clarke and the regulars at #SydMobNet who sat through my

Some great sessions today- here are some of the highlights: Think Like a Hacker! This was one of the most eye opening for many, with Darren Cathey going into great detail on security and protection against app hacking techniques to a packed room. These figures were quoted: Off the top

So here are today's announcements, along with links to find out more about each. Partnership with IBM Fruits of this partnership include: * IBM MobileFirst SDK for Xamarin, a pre-built library that Xamarin and IBM devs can include in their apps to connect, secure and manage apps using IBM

Today's sessions went into a lot more detail, which was great. Several of them were standing room only. The Enterprise Track talks on cloud services, data synchronisation and mobile security were particularly useful, as were the corridor / breakfast / lunch chats with Xamarin techies and other users.

When following the MVVM pattern your viewmodels should not communicate with each other directly, meaning no interdependencies. Navigation on the different platforms is from one view to another but we generally want to take control of the navigation structure at viewmodel level when coding cross platform apps (although admittedly, Xamarin

Introduction and Prerequisites The aim of this article is to get an app up and running across the three platforms, with all calls to Azure Mobile Services made from a cross platform portable class library (PCL), highlighting and resolving all the gotchas you might hit on the way. It assumes
