9. Why C#? C# is Awesome

10. Async programming
// C#
var user = await graphServiceClient.Me.Request().GetAsync();
// Do something...
// Java
graphServiceClient.getMe().buildRequest().get(new ICallback<User>() {
// Do something…
});
// Obj-C
[[[graphServiceClient me] request] getWithCompletion:^(MSGraphUser
*user, NSError *error){
// Do something…
}];

11. Native Performance

Time (AOT) compilation to
produce an ARM binary for
Apple’s App Store.

of Just In Time (JIT) compilation on
the Android device.
