title: System.ExecutionEngineException in wp8
body: <p>i am getting this exception while debugging my wp8 app on the device. System.ExecutionEngineException . Upon searching the net, i found suggestions to disable concurrent garbage collection and include that in app.config file. How can i do this on windows phone 8. I don't see that in my project. Where should i include this configuration.</p>
  
  <pre><code>&lt;configuration&gt;
  &lt;runtime&gt;
       &lt;gcConcurrent enabled="false"/&gt;
  &lt;/runtime&gt;
  &lt;/configuration&gt;
  </code></pre>
  
  <p>Kindly help on this.</p>
