title: Json in Web.Config AppSettings
body: <p>I am trying to put some mapping config represented in json:</p>
  
  <pre><code>[{"Name":"xyz","Ids":["456f782d468","c65b4703"]},{"Name":"abc","Ids":["a95fg567","456sdf564"]}]
  </code></pre>
  
  <p>Is it possible to store a json in appsettings?<br>
  I know I can create a custom section in web.config.<br>
  But this app may be deployed to Azure Web Apps where appsettings is the only way I see this config can go.</p>
