title: Displaying a pop-up right-click style menu in WinRT
body: <p>Strangely, I can't seem to find any details of how this is done in WinRT.  What I want is to display the menu which typically appears when you touch and hold, or right click an icon / image in Windows 8.  I found the event <code>Holding</code>, but that doesn't seem to do what I want, in that is doesn't seem to respond to the right mouse click.  Do both of these events need to be handled separately?  Are there any built in events, or does everyone have to roll their own?</p>
