Maps using Xaml

Hello,

is there an example on how to use xamarin.forms Maps into XAML?

I tried to use the tag Map but is not found.

Readng this example it seems specific code is needed for Android: https://github.com/xamarin/xamarin-forms-samples/blob/master/FormsGallery/FormsGallery/FormsGallery/MapDemoPage.cs

Is it correct?

Thanks
