ListBox and ListView block UI while adding many new items

Workarounds

Bing Maps SDK for metro style apps (beta)

Bing Maps API, static Picture with specified coordinates and manual implemented controls (zoom, etc)

Using of VisualTreeHelper to find a ScrollBox in ListViews

Using of PeriodicTimer to add new items
