title: Implementing ISupportIncrementalLoading in WPF and WP8
body: <p>WinRT applications have a simple way to add virtualization to ListView control. If a collection implements ISupportIncrementalLoading, it can be used for partial async loading of large number of items.</p>
  
  <p>I am trying to solve this task on other platforms: WPF and WP8. This interface is not available there but I wonder if there is an implementation that matches closely WinRT counterpart.</p>
