title: ASP.Net 5 RC2 configuration section binding
body: <p>I have just upgraded my sample app from RC1 to RC2 and I can't find how to bind a specific section of my appSettings.json file to my own POCO anymore.</p>
  
  <p>The sample at <a href="https://github.com/aspnet/live.asp.net/blob/rc2/src/live.asp.net/Startup.cs#L47" rel="noreferrer">https://github.com/aspnet/live.asp.net/blob/rc2/src/live.asp.net/Startup.cs#L47</a> show that something like this should work:</p>
  
  <pre><code>services.Configure&lt;AppSettings&gt;(options =&gt; Configuration.GetSection("AppSettings").Bind(options));
  </code></pre>
  
  <p>But with the final RC2 bits the "Bind" method or extension method can't be found</p>
  
  <p>Any idea where it lives now or if there is a new approach for this?</p>
