title: Can''t resolve CreateJsonReader
body: <p>I inherited some VB.NET code that has the following:</p>
  
  <pre><code>xmlreader = Json.CreateJsonReader(result, quotas)
  </code></pre>
  
  <p>I can't seem to resolve this reference. MSDN tells me its in <code>System.Runtime.Serilaization.Json</code> but if I type that with Intellisense I don't get to a Json namespace or the function. What am I doing wrong?</p>
  
  <p>It's also barfing on these two statements before it saying I should switch to something else:</p>
  
  <pre><code> Dim xmlreader As System.Xml.XmlDictionaryReader
   Dim quotas As New System.Xml.XmlDictionaryReaderQuotas
  </code></pre>
