I have customized Boris's answer to MVC Webapi 5. Use either of the following http headers render the result using the CustomFormatter:

accept: application/xml

accept: text/xml

WebApiConfig.cs :

public static class WebApiConfig
{
    public static void Register(HttpConfiguration config)
    {
        config.Routes.MapHttpRoute(
            name: "DefaultApi",
            routeTemplate: "{controller}/{id}",
            defaults: new { id = RouteParameter.Optional }
        );

        GlobalConfiguration.Configuration.Formatters.Add(new CustomXmlFormatter());
        GlobalConfiguration.Configuration.Formatters.Remove(GlobalConfiguration.Configuration.Formatters.XmlFormatter);
    }
}

CustomXmlFormatter.cs :

using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Net;
using System.Net.Http;
using System.Net.Http.Formatting;
using System.Net.Http.Headers;
using System.Text;
using System.Threading.Tasks;
using System.Web;
using System.Xml.Serialization;

namespace Custom.Formatter
{
    public class CustomXmlFormatter: MediaTypeFormatter
    {
        private  UTF8Encoding encoder;

        public CustomXmlFormatter()
        {
            SupportedMediaTypes.Add(new MediaTypeHeaderValue("application/xml"));
            SupportedMediaTypes.Add(new MediaTypeHeaderValue("text/xml"));
            encoder = new UTF8Encoding(false, true);
        }

        public override bool CanReadType(Type type)
        {
            if (type == (Type)null)
                throw new ArgumentNullException("type");

            //Type filtering
            if (type == typeof(SendEmailMessageResponse) || type == typeof(SendSmsMessageResponse))
                return true;
            else
                return false;
        }

        public override bool CanWriteType(Type type)
        {
            return true;
        }

        public override Task
