I need to do this as well and haven't found any way yet. Also struggling to catch memory warnings, which happens a lot if you use the carousel page.
yes this was logged on their bugzilla https://bugzilla.xamarin.com/show_bug.cgi?id=21995 (now resolved)
The bug that was breaking for me seems to be fixed now.
Have you tried the latest pre release version? https://www.nuget.org/packages/Xamarin.Forms/188.8.131.5284-pre3
