AnalogClock is a classic clock containing hour, minute, and second hands, with a circle of tick marks showing minutes and hours. A single solution contains versions for iOS, Android, and Windows Phone.
If you open the solution in Xamarin Studio, it will not be able to load the Windows Phone project; and if you open the solution in Xamarin Studio under Windows, it will not be able to load the iOS project either.
All three versions share a ClockModel class that implements the INotifyPropertyChanged interface, and provides angle values for the clock hands. The ClockModel class also creates a rudimentary timer using the await operator and the Task.Delay method.
All three versions draw the clockface ticks using a circle rendered with a dotted line. The iOS and Android versions draw the clock hands from code using a graphics path with Bezier curves. The Windows Phone version defines the clock entirely in XAML and is updated from the ClockModel class defined as a resource.
