.Net 4.0を使用してDocuSign RestApiを呼び出す

Question

DocuSign rest apiをC＃winフォームで使用する予定です。私は.Net 4.0を使用しています。ただし、DocuSign c# SDKは.NET 4.0をサポートしていません。

.Net 4.0を使用してDocuSignにC＃Winformsを使用するRestApiのサンプルコードはありますか？

以下は、.Net 4.0を使用してDocuSign REST APIに生のHTTP呼び出しを行う例です。私は、.NET 4.0

using System; 
using System.IO; 
using System.Net; 
using System.Text; 
using System.Windows.Forms; 

namespace DocuSignDotNet40 
{ 
    public partial class SignatureForm : Form 
    { 
    protected const string _username = ""; //Enter Username here 
    protected const string _integratorKey = ""; //Enter Integrator Key here 
    protected const string _password = ""; //Enter Password here 
    protected const string _baseUri = "https://demo.docusign.net/restapi"; //Enter baseUri here 
    protected const string _accountId = ""; //Enter acountId here 
    protected string _authHeader = ""; 

    private void CreateEnvelope_Click(object sender, EventArgs e) 
    { 
     string requestUrl = _baseUri + "/v2/accounts/" + _accountId + "/envelopes"; 
     var httpWebRequest = (HttpWebRequest)HttpWebRequest.Create(requestUrl); 
     httpWebRequest.Method = "Post"; 
     httpWebRequest.ContentType = "application/json"; 
     httpWebRequest.Headers.Add("X-DocuSign-Authentication", _authHeader); 

     string jsonRequest = GetCreateEnvelopeJson(); 
     var data = Encoding.ASCII.GetBytes(jsonRequest); 
     using (var stream = httpWebRequest.GetRequestStream()) 
     { 
      stream.Write(data, 0, data.Length); 
     } 
     var response = (HttpWebResponse)httpWebRequest.GetResponse(); 
     using (StreamReader sr = new StreamReader(response.GetResponseStream())) 
     { 
      string responseJson = sr.ReadToEnd(); 
      // more stuff 
     } 
    } 

    public string GetCreateEnvelopeJson() 
    { 
     return @"{

    } 
    public void GetEnvelope() 
    { 
     string envelopeId = "";//Enter EnvelopeId here 
     if(string.IsNullOrWhiteSpace(envelopeId)) throw new ApplicationException("Invalid Envelope Id"); 

     string requestUrl = _baseUri + "/v2/accounts/" + _accountId +"/envelopes/" + envelopeId ;

     using (StreamReader sr = new StreamReader(response.GetResponseStream())) 
     { 
      string responseJson = sr.ReadToEnd(); 
      // more stuff 
     } 

    } 

    public SignatureForm() 
    { 
     InitializeComponent(); 

     if (string.IsNullOrWhiteSpace(_username)) throw new ApplicationException("Invalid _username"); 
     if (string.IsNullOrWhiteSpace(_integratorKey)) throw new ApplicationException("Invalid _integratorKey");
