title: How to debug running out of memory on Windows Phone
body: <p>I am making a WP8 image processing app in c#, and am having some memory issues.</p>
  
  <p>If I navigate away from the app, and navigate back a bunch of times, I run out of memory (eg. Home -> back -> home -> back...). </p>
  
  <p>I was wondering how to debug this issue? I am trying to clean up memory as much as I can (using Dispose/setting things to null), but it isn't working.</p>
  
  <p>How would I debug it? Is there a way to find out how the memory is being used by what? </p>
