title: How do I implement an InfoWindowAdapter interface in Xamarin?
body: <p>I am using Xamarin and I am wanting to create a CustomWindowAdapter that implements a GoogleMap.InfoWindowAdapter interface.</p>
  
  <p>I have tried this so far:</p>
  
  <pre><code>public class CustomWindowAdapter : InfoWindowAdapter
  {
  
  }
  </code></pre>
  
  <p>I am getting this error:</p>
  
  <blockquote>
    <p>Error CS0246: The type or namespace name 'InfoWindowAdapter' could not be found (are you missing a using directive or an assembly reference?)</p>
  </blockquote>
  
  <p>Here is the documentation for the interface: <a href="https://developers.google.com/maps/documentation/android/reference/com/google/android/gms/maps/GoogleMap.InfoWindowAdapter" rel="nofollow">https://developers.google.com/maps/documentation/android/reference/com/google/android/gms/maps/GoogleMap.InfoWindowAdapter</a></p>
  
  <p>Can I please have some help? </p>
  
  <p>What using statement do I need to use?</p>
  
  <p>Thanks in advance</p>
