Let us draw polygons with holes on the MapControl
Currently, there's a bug where polygons won't render when they overlap themselves (see https://social.msdn.microsoft.com/Forums/windowsapps/en-US/04bf003a-f15d-446a-8f70-3fa96905c303/map-polygons-with-holes-in-windows-phone-81)
So it's currently impossible to draw polygons with holes, which e.g. makes it impossible to draw complex buildings etc.
Fixed in Anniversary Update

my app use data provided from my government (means i have no control on the data) and experience the same problem, the polygons are not drawn, unfortunately its no problem with android and ios :-( so PLEASE implement this!

Real blocker when you need to draw geometry into maps. Is it true that it won't be fixed in Windows Phone 10? Horrible and unprofessional approach :(. Unfortunately, we are pushed to develop for this platform and have to cope with it.
