Native Performance
Xamarin.iOS does full Ahead Of
Time (AOT) compilation to
produce an ARM binary for
Apples App Store.
Xamarin.Android takes
advantage of Just In Time
(JIT) compilation on the
Android device.
Code Sharing: Accelerate Development
Up to 90% Code Reuse
Leverage existing libraries
Code-sharing stats from iCircuit, built with Xamarin and featured
on the App Store.

Rdio Case
Study
About Rdio
Rdio is the leading music
streaming and sharing
service started by the
founders of Skype
Rdio is already in 30
countries with over 20
million songs.
Available in 31 countries
Wired Magazine
Rdios mobile app is also the best looking and best
implemented of the three [music streaming apps reviewed].
Sharing 50,000 lines of code
Challenge
Unable to deliver features on all
platforms simultaneously because of
multiple, platform-specific code bases
High costs to development and
maintain apps
!
Results
Using Xamarin, Rdio now shares over 50,000 lines of
C# across iOS, Android, and Windows, enabling them to
focus on feature-parity and user experience.
Sharing 50,000 lines of code
Xamarin offers the best of all worlds. We
deliver high performance, native apps that,
until Xamarin, were only possible with
Objective-C and Java. Sharing over 50,000
lines of code across platforms gives us more
time to spend on great user experiences.
