title: Image tag in WPF in .net core 3.0 not working
body: <p>I am working on a WPF application using .net core 3.0 preview.</p>
  
  <p>I tried the following line of <code>xaml</code> code in both <code>.net core 3.0 preview</code> and <code>.net framework</code>.</p>
  
  <pre class="lang-xml prettyprint-override"><code>&lt;Grid&gt;
      &lt;Image Source="system-tray.jpg"/&gt;
  &lt;/Grid&gt;
  </code></pre>
  
  <p>This works fine in <code>.Net Framework</code> but doesn't work in <code>.Net Core 3.0 preview</code></p>
  
  <p>Any thoughts!..</p>
