“MVVM is awesome and will revolutionize your application
development process.”-James Montemagno
Let’s talk architecture(because that is fun)
Well First…. What is Xamarin?
Mobile Development Approaches
Single App
OR OR
Silo Approach
Write Once, Run Anywhere Approach
Lowest common denominator
App Generation
Write Once, Run Anywhere Approach
Lowest common denominator
App Generation
Xamarin’s Unique Approach
C# on 2.6 Billion Devices
100% API Coverage
Anything you can do in Objective-C or Java can be done in C# and Visual Studio with
Xamarin!
Xamarin.iOS does full Ahead Of Time (AOT) compilation to produce an ARM binary for Apple’s App Store.
Native Performance
Xamarin.Android takes advantage of Just In Time (JIT) compilation on the Android device.
Code Sharing: Accelerate Development

For real, let’s talk architecture
Why do we use them?•Organize & Maintain Code•Abstract away all business logic
•Re-use a high percent of our code
•Make our views dumb!•Our architect told us to
What is MVC?
Model-View-Controller
Model
View Controller
Updates
Sees Uses
Manipulates
What is MVVM?
Model-View-ViewModel
ModelView ViewModel
How to display information
What to displayFlow of interaction
Business LogicData objects
Events
DataData
MVVM != Data Binding
MVVM Framework == Data Binding
