I got solution, I just added below two lines in WebApiConfig
var json = config.Formatters.JsonFormatter;
json.SerializerSettings.PreserveReferencesHandling = Newtonsoft.Json.PreserveReferencesHandling.Objects;
config.Formatters.Remove(config.Formatters.XmlFormatter);

Your code is perfectly alright.

Just check the order of configuration settings under Application_Start() event in Global.asax file.

AreaRegistration.RegisterAllAreas();
FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
GlobalConfiguration.Configure(WebApiConfig.Register);
RouteConfig.RegisterRoutes(RouteTable.Routes);
BundleConfig.RegisterBundles(BundleTable.Bundles);

WebApiConfig.Register This is for API configuration and has to be before RouteConfig configuration.

Happy Coding!
