title: LongListSelector and context menu
body: <p>I have a collection of objects which I want to display as a list. So, I'm binding a <code>LongListSelector</code> with this collection. All the items in the collection appear in the form of list. The next thing I want to do is when the user make long press on an item so it will popup a little windows with delete,add and another options.</p>
  
  <p>How i should do it? i search in a lot of places and didn't find nothing about LongListSelector and context menu </p>
