  <p>What I have tried </p>
  
  <p><strong>Reinstalling Xamarin.Android.Support.Design</strong></p>
  
  <ul>
  <li>It started showing me a similar error for the
  Xamarin.Android.Support.v7.MediaRouter package </li>
  <li>When I tried to    reinstall the
  Xamarin.Android.Support.v7.MediaRouter it started    showing the
  error message for the  Xamarin.Android.Support.Design    package
  again</li>
  </ul>
  
  <p><strong>Downloading the missing files</strong></p>
  
  <ul>
  <li><p>Downloaded the zip file at <a href="https://dl-ssl.google.com/android/repository/android_m2repository_r29.zip" rel="noreferrer">https://dl-ssl.google.com/android/repository/android_m2repository_r29.zip</a></p></li>
  <li><p>Extracted the content of the design folder and copied it to C:\Users\Kareem\AppData\Local\Xamarin\Xamarin.Android.Support.Design\23.0.0\content\</p></li>
  </ul>
  
  <p>nothing worked and I'm now stuck and couldn't think of anything else to try</p>
