JavaScriptSerializer seems to ignore the maxJsonLength configuration

Question

I was facing the max json length problem so as suggested by various sources on the internet, i increased the default json length in the configuration file like

<system.web.extensions>
    <scripting>
      <webServices>
        <jsonSerialization maxJsonLength="900000000"></jsonSerialization>
      </webServices>
    </scripting>
  </system.web.extensions>

but the problem persisted. Then i came across a fantastic blog post that suggested to write my own ActionResult. i am using the telerik grid for mvc along with mvc3.net. Any idea why the serializer ignoring the config.

MaxJsonLength and ASP.NET MVC

In ASP.NET MVC, it seems you need to set the MaxJsonLength during the execution:

public JsonResult GetData()
{
    var model = GetModel();

    var outputJsonResult = Json(model);
    outputJsonResult.MaxJsonLength = 10 * 1024 * 1024; // 10 MB

    return outputJsonResult;
}

Having struggled with this myself, unfortunately, for now, this is the only solution.
