Just to let you know. I've ported the latest ViewPagerIndicator library, which you can get here: https://github.com/Cheesebaron/ViewPagerIndicator
The one in monodroid-samples is a bit old and does not have the latest bugfixes, neither does it use C# events for PageChange listeners nor does it use Properties to expose things that can be styled and adjusted.
I've also ported all the samples for you to look at. Enjoy!
