title: send email with attachments
body: <p>My problem is very simple. I need to send e-mail with recipients and attachments which I generate in C#.</p>
  <h1>1 method:</h1>
  <pre><code>var mailto = new Uri(&quot;mailto:?to=&quot; + emails + &quot;&amp;subject=&quot; + subject + &quot;&amp;body=&quot; + body);
          await Windows.System.Launcher.LaunchUriAsync(mailto);
  </code></pre>
  <p>It's ok but I cannot add attachments (only recipients)</p>
  <h1>2 method:</h1>
  <p>Using <code>DataTransferManager</code>. It's very cool but I can't add recipients.</p>
  <p>Is there any method to solve my problem ?</p>
