title: JsonProperty based on webconfig
body: <p>I have a question about JsonProperty on the field.</p>
  
  <p>Is it possible to pass a propertyName from WebConfig?</p>
  
  <p>I need it for my application because I have two different "types":</p>
  
  <p>production -> use for clients
  test -> use for developers.</p>
  
  <p>In my webconfig in-app settings I want to set JsonProperty name, something like this:</p>
  
  <pre><code>[JsonProperty(value from app settings)]
  
  &lt;appSettings&gt;
      &lt;add key="Version" value="test" /&gt; or value="production"
  &lt;/appSettings&gt;
  </code></pre>
  
  <p>Is there any option for doing this?</p>
