title: How to handle OutOfMemoryException when a list gets too big?
body: <p>My application has two lists</p>
  
  <pre><code>public ObservableCollection&lt;StreamItemViewModel&gt; SearchStreamItems { get; private set; }
  public ObservableCollection&lt;StreamItemViewModel&gt; MyStreamItems { get; private set; }
  </code></pre>
  
  <p>And each are the DataSource of one <code>ListBox</code>. Each time I click the button <code>more</code> the applications load 100 new items, and after a few clicks it throws a <code>OutOfMemoryException</code>.</p>
  
  <p>Is there a way to avoid the exception? Or what should I do? Stop loading more updates?</p>
