The document provides an overview of Xamarin, a platform for building mobile apps using C# that can target iOS, Android and Windows. It discusses Xamarin's approach of allowing developers to share C# code across platforms while still providing native user experiences. It also covers Xamarin tools and features like Xamarin.Forms for building user interfaces, plugins for accessing native device capabilities, and services for testing, building, and distributing mobile apps. The document aims to introduce developers to Xamarin and help them get started with mobile development using the platform.

Editor's Notes
- Xamarin is your complete mobile solution. Xamarin Platform is usually what you hear about which is building native iOS, Android, Mac, and Windows Apps all in C# However Xamarin offers a wide range of products for developers to go mobile including Test Cloud, Hockey App, and a way to learn all of mobile with University.

- Multiple Teams Multiple Code Bases Expensive & Slow Positive = Great apps delivered to user’s platform Negative = Development hampered by multiple code bases & fragmentation
- UI build natively per platform, leveraging C# C# + XAML C# + XML C# + XIB One shared app logic code base, iOS, Android, Mac, Windows Phone, Windows Store, Windows
- You can think of iOS and Android development the same with Xamarin. You can see we have all of our .NET namespaces and libraries, but Xamarin give us 100% api coverage of each iOS API in it’s SDK that we access view C#.
- The same is true for Android as well.
- Single Solution for iOS, Android, and Windows Leverage Entire Microsoft Ecosystem: ReSharper Team Foundation Server Azure ASP.NET Favorite Code Coverage and Profiling Tools Starter Compatible Visual Studio 2012, 2013, and 2015 including Community Edition
- Xamarin Studio on Mac offers: Android, iOS and Mac development World Class IDE with great features: Code Analysis Upload to Test Flight Git & Subversion Integration Code Completion Code Navigation Easy transition from Visual Studio The same Solution & Projects open in BOTH Xamarin Studio and Visual Studio!
- Xamarin Forms is a new set of APIs allowing you to quickly and easily write shared User Interface code that is still rendered natively on each platform, while still providing direct access to the underlying SDKs if you need it.
- We see here the Xamarin approach we talked about earlier This enables you to be highly productive, share code, but build out UI on each platform and access platform APIs With Xamarin.Forms you now have a nice Shared UI Code layer, but still access to platform APIs You can start from native, pick a few screens, or start with forms, and replace with native later
- First you have a set of pages for each screen of your application There are things like Content, and MasterDetail which gives you a nice flyout With a tabbed view you get the correct look on each platform iOS on bottom, Android on top, and on WP you have a Pivot control Inside of a page are layouts A lot of options from something simple like a stack panel to complex and powerful grids
- You have more than 40 controls, layouts, and pages to mix and match from. These are all of the controls you have out of the box, you can of course create your own. What is unique is you get the native control and have access to it. Consider an Entry Field On iOS it is mapped to UITextField Android it is EditText Windows Phone it is a TextBox
- A unique aspect of Xamarin.Forms is an abstraction over the user interface, but what about the platform specific functionality that makes these devices so special? That is where plugins for Xamarin come in.
- What is this stuff that we talk about up here?
- This is the platform specific code no matter how you are developing traditional Xamarin or with Xamarin.Forms. However, many platform APIs are the same bit of functionality, but with different APIs. What if we had 1 API?
- For instance text to speech, what if we could just say “Speak” and it would speak text with the underlying API.
- This is what Plugins for Xamarin are for! 1 API for all common APIs: Camera GPS Settings Notifications Battery And so much more!

Xamarin Platform is usually what you hear about which is building native iOS, Android, Mac, and Windows Apps all in C# However Xamarin offers a wide range of products for developers to go mobile including Test Cloud, Hockey App, and a way to learn all of mobile with University.
- Well there are several challenges that we must overcome as mobile developers including….
- First let’s take a look at the shear number of configurations there are between iOS and Android. As iOS progresses this number is only set to increase, and on Android it is already a HUGE number of configurations to even think about testing. iOS: 7, 7.1, 8, 8.1, 8.2
- OpenSignal is a global app that publishes an annual report on Android device fragmentation based on the distinct Android device types that download their app. This is their August 2015 data, with an astonishing 24,000 device types using their app, up by 60% from just last year. Different device operating systems, form factors, screen sizes, resolutions, chip sets, and manufacturer modifications make it difficult to know that your app will work well on all devices
- Looking at just a few of the screen sizes of Samsung devices you couldn’t even fit all of them on the screen, so how do you handle this problem?
- This is where Xamarin.UITest comes in to help with this shift. Xamarin.UITest is a framework that ties in directly to the Nunit testing framework to write the UI tests. You can even run them directly against a simulator for free to do regression tests on your applications. Freely available for testing on a Simulator*
- Take test scripts and test again thousands of physical devices! All Xamarin subscribers get free device time! Check store.xamarin.com for details.
