- 12. Extensibility Embed Custom Views Anywhere Not only are Xamarin.Forms pages mixable with custom screens, you can embed custom views built directly against Xamarin.iOS and Xamarin.Android into Xamarin.Forms pages. Call Platform APIs via Shared Services Need platform-specific functionality within a Xamarin.Forms page, such as querying the accelerometer? We’ve included services that quickly and easily abstract platform-specific API calls to keep you writing as much shared code as possible. Easy migration to the Xamarin Platform When your native platform integration requirements outgrow Xamarin.Forms, your shared code is easily migrated to Xamarin.iOS and Xamarin.Android using the full Xamarin platform.

Editor's Notes
- #4: 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.
- #7: 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
- #8: If you have ever developed for a Windows Platform before these .NET namespaces might look familiar. However, if we go to a new platform such as Windows Phone or Store we have a new SDK to use and a new set of namespaces.
- #9: 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#.
- #10: The same is true for Android as well.
- #11: For instance text to speech, what if we could just say “Speak” and it would speak text with the underlying API.
- #14: 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
- #15: 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!
- #17: 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.
- #18: 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
- #19: Xamarin.Forms is much more that just a framework and includes everything you need to get up and running to build out full native applications. If you are used to MVVM type of development you will feel right at home.
- #20: 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
- #24: Here is a quick example of a login page: Notice the data binding on the Entries Text fields. Additionally, there is a LoginCommand. Each has a native user interface
- #26: 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.
- #27: 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
- #28: With a simple command you can simulate all of your users interactions to build out a great test suite that can be run over and over again.
- #29: Take test scripts and test again thousands of physical devices! All Xamarin subscribers get free device time! Check store.xamarin.com for details.
- #30: 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*
