AI is not taking over our planet just yet, but we're getting there! In this session we will look at how we can integrate the Microsoft Cognitive Services into our Xamarin apps. With doing so, you can now determine what your users are looking at and even how they are feeling and use that to enhance your functionality. "Come with me if you want to live!"

Security is a major focus when building web applications. But what about app security? What do I have to look out for as a developer to write a secure app? How do I handle sensitive data, and what should I consider when designing a service to be consumed by apps? In this session, you'll learn the different potential security issues and the corresponding solutions for mobile developers to consider when beginning a mobile development project.

Each time you pick up a training manual to learn something new in software, you'll probably simultaneously also open up your computer to try out small code snippets. Nothing more frustrating to get out of the reading flow and switch your focus to the IDE while trying the code samples. Thanks to Xamarin Workbooks, this is now something of the past! Workbooks enables live documentation, meaning you can read the tutorial and have code sampling directly integrated in the learning environment. During this session, we'll show you how to use and create Workbooks to help users engage and interact more with your tutorial or samples.

Although Reactive Programming is well known to be a good paradigm for reliable Apps the effort it takes to make the necessary mind shift is quite hard which stops most developers before they even start. My goal is it to give developers with intermediate knowledge of Xamarin Forms development and experienced ones without experience with the Rx World a good impression what it can do for you in your daily live to get the motivation to start with Reactive Programming. This won't be a introduction that goes deep into the details of Rx or ReactiveUI but a presentation and explanation of real-world code examples that are easy to follow.

In this session Pieter will show you exactly why Realm is such a hot topic at the moment. He will start of simple with a local data storage example, but will quickly change gears and show you where Realm really shines: connecting to a remote Realm Object Server, building a realtime collaboration app that does realtime data synchronisation, creating serverless functions that get triggered when data is pushed to the remote data store. And what about offline capabilities, networking code, conflict resolution? Don't you worry about that! After this session you won't believe how easy it is to build these kind of complex looking things with Realm in no time!

Is building a mobile backend in the cloud any different compared to building a mobile backend on premise? It sure can be! Join this session to learn how to use cloud native components in Azure and what impact this has on your Xamarin app. We'll look at different options to implement your backend by using DocumentDB, Azure Functions and Azure Mobile Apps.
