title: Chart Control needs an HTTP Handler?
body: <p>I have an VS2010 ASP.NET 4 web site app, to which I added the new Chart control.</p>
  
  <p>When I deployed it to our web server, we get a" Internal Server Error 500." message.</p>
  
  <p>I noticed that the following lines were added to the web.config since the last release, related to the chart control:</p>
  
  <pre><code>  &lt;system.web&gt;
      &lt;httpHandlers&gt;
        &lt;add path="ChartImg.axd" verb="GET,HEAD,POST" type="System.Web.UI.DataVisualization.Charting.ChartHttpHandler, System.Web.DataVisualization, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"
         validate="false" /&gt;
      &lt;/httpHandlers&gt;
  </code></pre>
  
  <p>If I remove this added code from the web.config, the site works--Except for the charting functionality.</p>
  
  <p>How do I get the site and the chart page to work?</p>
  
  <p>This is not an issue on IIS versions &lt; 7.</p>
