title: Error when building Xamarin project
body: <p>I'm receiving this error everytime i try to build my xamarin project</p>
  
  <pre><code>Can not resolve reference: `Parse`, referenced by `Project`. Please 
  add a NuGet package or assembly reference for `Parse`, or remove the reference 
  to `Project`.   Project.Android
  </code></pre>
  
  <p>So far I've tried:</p>
  
  <ul>
  <li>Deleting all the folders in packages > restarting VS2017</li>
  <li>Running VS2017 as Admin</li>
  </ul>
  
  <p>None of those worked, anyone has any idea how to fix this?</p>
  
  <p>Thanks in advance.</p>
