title: Content '\/Date('')\/' does not start with '\/Date(' and end with ')\/' as required for JSON
body: <p>I want to send a post request to a WCF rest service as you can see:</p>
  
  <pre><code>Guid id;
  id = Guid.NewGuid();
  
  var httpWebRequest = (HttpWebRequest)WebRequest.Create("http://localhost:47026/NewsRepository.svc/AddNews");
  httpWebRequest.ContentType = "application/json";
  httpWebRequest.Method = "POST";
  using (var streamWriter = new StreamWriter(httpWebRequest.GetRequestStream()))
  {
      string json = new JavaScriptSerializer().Serialize(new
      {       
          id = id,
          Subject="wfwf",
          ViewerCounter="1",
          Content="fsdsd",
          SubmitDatatime="2012/12/12",
          ModifiedDateTime="2012/12/12",
          PublisherName="sdaadasd",
          PictureAddress="adfafsd",
          TypeOfNews="adsadaad"                       
      });
  
      streamWriter.Write(json);
  }
  try 
  { 
      var httpResponse = (HttpWebResponse)httpWebRequest.GetResponse();
      using (var streamReader = new StreamReader(httpResponse.GetResponseStream()))
      {
          var result = streamReader.ReadToEnd();
      }
  }
  catch(Exception er)
  {
      MessageBox.Show(er.ToString());
  }
  </code></pre>
  
  <p>But I get an error - 400 bad request. So I traced my WCF log file and I found this error:</p>
  
  <blockquote>
    <p>There was an error deserializing the object of type CMSManagement.Domain.Entity.News. DateTime content '2012/12/12' does not start with '/Date(' and end with ')/' as required for JSON.</p>
  </blockquote>
  
  <p>After my dear friend @svek code. The result is like this:</p>
  
  <pre><code>Guid id;
  id = Guid.NewGuid();
  
  var httpWebRequest = (HttpWebRequest)WebRequest.Create("http://localhost:47026/NewsRepository.svc/AddNews");
  httpWebRequest.ContentType = "application/json";
  httpWebRequest.Method = "PUT";
  using (var streamWriter = new StreamWriter(httpWebRequest.GetRequestStream()))
  {
      JsonSerializerSettings microsoftDateFormatSettings = new JsonSerializerSettings
      {
          DateFormatHandling = DateFormatHandling.MicrosoftDateFormat
      };
  
      string json = JsonConvert.SerializeObject(new
      {
          id = id,
          Subject = "wfwf",
          ViewerCounter = "1",
          Content = "fsdsd",
          SubmitDatatime = "2012/12/12",
          ModifiedDateTime = "2012/12/12",
          PublisherName = "sdaadasd",
          PictureAddress = "adfafsd",
          TypeOfNews = "adsadaad"
      }, microsoftDateFormatSettings);
      streamWriter.Write(json);
  }
  try 
  { 
      var httpResponse = (HttpWebResponse)httpWebRequest.GetResponse();
      using (var streamReader = new StreamReader(httpResponse.GetResponseStream()))
      {
          var result = streamReader.ReadToEnd();
      }
  }
  catch(Exception er)
  {
      MessageBox.Show(er.ToString());
  }
  </code></pre>
  
  <p>But I get the same error. Why?</p>
