            // To disable tracing in your application, please comment out or remove the following line of code
            // For more information, refer to: http://www.asp.net/web-api



            var json = config.Formatters.JsonFormatter;
            json.SerializerSettings.PreserveReferencesHandling =
                Newtonsoft.Json.PreserveReferencesHandling.None;

            config.Formatters.Remove(config.Formatters.XmlFormatter);
            config.EnableSystemDiagnosticsTracing();
        }
    }
}

Getting the below Error:-

'System.Web.Http.HttpConfiguration' does not contain a definition for 'EnableQuerySupport' and no extension method 'EnableQuerySupport'
accepting a first argument of type 'System.Web.Http.HttpConfiguration'
could be found (are you missing a using directive or an assembly
reference?)

Best Answer

In Visual Studio go to "Tools" and then "Nuget Package Manager" and then "Package Manager Console"

Run the below command and it will fix the issue. Have tested it.

update-package microsoft.aspnet.webapi -reinstall
