title: Host a standard UWP control in a WPF app using XAML Islands
body: <p>I have used the following example to host a standard UWP control in a WPF app using XAML Islands:
  <a href="https://docs.microsoft.com/en-us/windows/apps/desktop/modernize/host-standard-control-with-xaml-islands" rel="nofollow noreferrer">https://docs.microsoft.com/en-us/windows/apps/desktop/modernize/host-standard-control-with-xaml-islands</a></p>
  
  <p>But if I get to the point:</p>
  
  <blockquote>
    <ol start="8">
    <li>In your WPF project, right-click the Dependencies node and add a reference to your UWP app project.</li>
    </ol>
  </blockquote>
  
  <p>I get the following error: </p>
  
  <blockquote>
    <p>Unable to add a reference to project…</p>
  </blockquote>
  
  <p>Why isn't this working?</p>
