@exim: That doesn't really relate to this video and I don't work on that team, but I assume not as they are Hyper-V enabled and their docs say: ou can only install the Visual Studio Emulator for Android on an operating system where Hyper-V is supported. Examples of where Hyper-V is not supported include Windows 7, non-Windows machines, and inside another Hyper-V VM.
Xamarin.iOS and Xamarin.Android are the backbone to Xamarin.Forms, without them it wouldnt' be possible to have Xamarin.Forms when you think of how the abstraction is created. Additionally, traditional Xamarin will give you the pure access to every since control, full storyboard support/android xml, and so much more that developers love when they want to get right to the metal of each platform.
@SoylentGreen: I am working on each episode, sometimes there just isn't a lot of "code" to share, but I have just updated the repo and will be adding them in the show notes as well.
@JonasR: So "Components" are libraries specific to iOS/Android such as google play services or facebook SDKs. Plugins are amazing and I actually have made a lot that you will see on that page is an abstraction of platform specific APIs into an easy to use cross platform API. The easiest way to add platform specific functionality.
