c# - Why can't I see buildings on my bing map? -

i can't understand why bing map doesn't show buildings. showbuildings true.

you can compare 2 screenshots , difference huge.first - bing maps windows store appp (my app) second - native bing maps within windows 8 pro

my xaml pretty simple.

<mapscore:map x:name="part_map" credentials="string_key" showbuildings="true" showbreadcrumb="true" shownavigationbar="true" />

what wrong?

according this website, features of bing maps api (like birdseye imagery) not available public testing yet, , available through extended modes sdk. may problem coming from.
