title: XmlDocument type not found even though I've referenced System.XML?
body: <p>I've referenced System.Xml:</p>
  
  <pre><code>using System.Xml;
  </code></pre>
  
  <p>Then in this line:</p>
  
  <pre><code>XmlDocument xdoc = new XmlDocument();
  </code></pre>
  
  <p>I get:</p>
  
  <blockquote>
    <p>The type or namespace name
    'XmlDocument' could not be found</p>
  </blockquote>
  
  <p>What could there possibly be wrong ?</p>
  
  <p>Info:</p>
  
  <p>.NET 3.5, C#, triple checked that it's referenced and used in the same document, been able to use similar and even child libraries (System.Linq;System.Xml.Linq;System.Xml.XPath; System.Xml;)</p>
