title: Can't resolve XmlDictionaryWriter?
body: <p>I have some VB.NET code that I am converting to C#. It uses <code>XmlDictionaryWriter</code> and XmlDictionaryReaderQuotas both of which, according to MSDN are in System.Xml and in the assembly <code>System.Runtime.Serialization</code>. I added <code>System.Runtime.Serialization</code> as a reference. It keeps saying they cannot be found. Here is the VB.NET code:</p>
  
  <pre><code>Dim xmlreader As System.Xml.XmlDictionaryReader
  
  Dim quotas As New System.Xml.XmlDictionaryReaderQuotas
  
  xmlreader = JsonReaderWriterFactory.CreateJsonReader(result, quotas)
  </code></pre>
  
  <p>This is in VS2013/.NET Framework 4</p>
