Request JSON using WCF DS 5.0

So, I was start using WCF OData Services 5.0.1.0 and when I made an ajax call requesting the response in JSON I get the 415 error: "Unsupported media type requested".

Detail: "A supported MIME type could not be found that matches the acceptable MIME types for the request. The supported type(s) 'application/atom+xml;type=feed, application/atom+xml, application/json;odata=verbose' do not match any of the acceptable MIME types 'application/json'".

This happens because the serialization json light format will be part of the OData v3 protocol: "The new serialization format will be part of the OData v3 protocol, and we believe that the much-improved JSON format should be the default response when requesting application/json." (http://blogs.msdn.com/b/astoriateam/archive/2012/04/11/what-happened-to-application-json-in-wcf-ds-5-0.aspx)

In conclusion, you have the next code on your WCF OData Service:

public class api : DataService <DataModel>
{
 public static void InitializeService(DataServiceConfiguration config)
 {
  config.SetEntitySetAccessRule("*", EntitySetRights.AllRead);
  config.DataServiceBehavior.MaxProtocolVersion = DataServiceProtocolVersion.V3;
 }
}

And to call the service using javascript/jquery you can use the next code for that:

$.ajax({
  type: "GET",
  url: "api.svc/Entity()?$top=10",
  dataType: "json",
  beforeSend: function (xhr) {
    xhr.setRequestHeader("Accept", "application/json;odata=verbose");
  },
  success: function (data) {
    //success func
  },
  error: function (error) {
    //error func
  }
});
