Adding Management Certificate programatically to Azure using Azure Rest API

Question

IM trying to add a management certificate programmatically using Windows Azure Service Management REST API Reference

Below is the snippets used

public async void AddManagmentCertificate(string subscriptionId, string version)
        {
            string hittingurl = "https://management.core.windows.net/{0}/certificates";
            hittingurl = String.Format(hittingurl, "subidgoeshere");
            XmlDocument addcertDoc = await HelperMethods.PostXmlDocument(hittingurl,"2012-03-01");
            XmlNamespaceManager nsmgr = new XmlNamespaceManager(addcertDoc.NameTable);
            nsmgr.AddNamespace("rest", xmlnamespace);
            if (addcertDoc != null)
            {
                XmlNodeList certadded = addcertDoc.SelectNodes("//rest:SubscriptionCertificateThumbprint", nsmgr);

                if (certadded.Count > 0)
                {
                    string thumbprint = certadded[0].InnerXml.ToString();
                    if (String.IsNullOrEmpty(thumbprint))
                    {

                    }
                    else
                    {
                        LoadData();
                    }
                }


            }



        }


 public static async Task<XmlDocument> PostXmlDocument(string hittingUrl,string Version)
        {
            HttpWebRequest request;
            XmlDocument responsebody = new XmlDocument();


            Uri uri = new Uri(hittingUrl);


            request = (HttpWebRequest)HttpWebRequest.Create(uri);

            request.Method = "POST";
            request.Headers.Add("x-ms-version", Version);
            string certpath = HttpContext.Current.Server.MapPath(@"Certificates\epgwin8dashboard.cloudapp.net.cer");

            request.ClientCertificates.Add(X509Certificate2.CreateFromCertFile(certpath));

            request.ContentType = "application/xml";
            request.ContentLength = 0;




            HttpWebResponse webresponse = null;

            try
            {

                webresponse = (HttpWebResponse)await request.GetResponseAsync();


            }
            catch (Exception)
            {

            }

            HttpStatusCode statuscode = webresponse.StatusCode;
            if (webresponse.ContentLength > 0)
            {
                using (XmlReader reader = XmlReader.Create(webresponse.GetResponseStream()))
                {
                    responsebody.Load(reader);


                }
            }

            if (statuscode.Equals(HttpStatusCode.OK))
            {

                return responsebody;

            }
            else
            {
                return null;
            }


        }

Please tell me what else need to be enhanced to make this working with out errors

Try this code. I created a simple console application for this.

using System;
using System.Collections.Generic;
using System.Globalization;
using System.IO;
using System.Linq;
using System.Net;
using System.Text;
using System.Threading.Tasks;
using System.Xml;
using System.Security.Cryptography;
using System.Security.Cryptography.X509Certificates;

namespace StackOverflowAddManagementCertificate

    class Program

        private static string requestPayloadFormat =
            @"<SubscriptionCertificate xmlns=""http://schemas.microsoft.com/windowsazure"">

        private static string subscriptionId = "your subscription id";

        private static string certificateThumbprint = "certificate thumbprint for validating service management API request";

        private static string x_ms_version = "2012-03-01";

        private static string certificateFile = @"full path of the certificate file which needs to be uploaded e.g. D:\mytest1.cer";
        static void Main(string[] args)
