title: Web.Config <appsettings> section breaks site
body: <p>ASP.Net Data Retrieval site now erroring due to MS Patch limiting keys.
  Trying to put the following section into web.config to up the number of keys</p>
  
  <pre><code>&lt;appsettings&gt;
     &lt;add key="aspnet:MaxHttpCollectionKeys" value="2000"&gt;&lt;/add&gt;
  &lt;/appsettings&gt; 
  </code></pre>
  
  <p>Adding the section causes an Internal Server Error 'The configuration section 'appsettings' cannot be read because it is missing a section declaration'</p>
  
  <p>Any idea how to correctly add this section? I have tried variations of examples on the Web but I can't get past this.</p>
