title: XmlDocument availability
body: <p>I'm trying to deal with xml in a uwp app, I have added reference and usings:</p>
  
  <pre><code>using System.Xml;
  using System.Xml.XPath;
  </code></pre>
  
  <p>But a <code>private XmlDocument doc;</code> throws the compiler error:</p>
  
  <blockquote>
    <p>Error  CS0246  The type or namespace name 'XmlDocument' could not be found (are you missing a using directive or an assembly reference?)</p>
  </blockquote>
  
  <p>When I check the doc <a href="https://msdn.microsoft.com/en-us/library/windows/apps/system.xml.xmldocument.aspx" rel="nofollow noreferrer">here</a> it clearly says it is available in uwp since windows 10:</p>
  
  <pre><code>Version Information
  
  Universal Windows Platform 
  Available since 10
  .NET Framework 
  Available since 1.1
  </code></pre>
  
  <p>This type is also in .net core <a href="https://docs.microsoft.com/en-us/dotnet/core/api/system.xml.xmldocument" rel="nofollow noreferrer">too</a>.</p>
  
  <p>What should I do to use this type in the app?</p>
