config.Formatters.XmlFormatter.UseXmlSerializer = true;
config.Formatters.XmlFormatter.MediaTypeMappings.Add(new QueryStringMapping("$Format", "xml", "application/xml"));
config.Formatters.XmlFormatter.MediaTypeMappings.Add(new QueryStringMapping("OutputFormat", "xml", "application/xml"));
config.IncludeErrorDetailPolicy = IncludeErrorDetailPolicy.Always;
 
var serializerSettings =
  GlobalConfiguration.Configuration.Formatters.JsonFormatter.SerializerSettings;
var contractResolver =
  (DefaultContractResolver)serializerSettings.ContractResolver;
contractResolver.IgnoreSerializableAttribute = true;
//config.Formatters.Insert(0, new JsonpFormatter());
config.Formatters.JsonFormatter.SerializerSettings.ReferenceLoopHandling = Newtonsoft.Json.ReferenceLoopHandling.Ignore;
config.Formatters.JsonFormatter.SerializerSettings.PreserveReferencesHandling = Newtonsoft.Json.PreserveReferencesHandling.None;
config.Formatters.JsonFormatter.SerializerSettings.ContractResolver = new CamelCasePropertyNamesContractResolver();
config.Formatters.JsonFormatter.MediaTypeMappings.Add(new QueryStringMapping("$Format", "json", "application/json"));
config.Formatters.JsonFormatter.MediaTypeMappings.Add(new QueryStringMapping("OutputFormat", "json", "application/json"));
