Editor's Notes
- #6: DependencyService: For implementing platform-specific features such as geolocation or Bluetooth MessagingCenter enables view models and other components to communicate with without having to know anything about each other besides a simple Message contract. It can be used to send and receive simple messages or pass an argument between classes.
- #8: Inside of a page are layouts A lot of options from something simple like a stack panel to complex and powerful grids Elements: Page Layout View
- #9: 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
- #18: Explain Simple form (code vs. XAML) Add new form and swap with new XAML form Create a new XamlPlusCodePage Review MonkeyTap
- #20: Apple has a developer preview where Xamarin has alphas ready. Google does not offer this. Android versions are usually 4 to 8 weeks out for a stable release, but alphas and betas are usually earlier. Xamarin realizes how important having iOS ready because within 24 hours a large portion of iOS users upgrade Android on the other hand is much different. After 4 months on the market Android 4.4 only had 1% adoption
- #28: 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.

- #35: Easily embed any native control into a Xamarin.Forms layout.
- #36: Just add it as child to a layout. Exposed as an Extension Method.
