title: REST Hammock not adding content to post body
body: <p>I've been fiddling a POST request that isn't working. What I've found is that the content of the request is empty even though I believe I'm adding it correctly (even though there aren't any docs available that I can find).</p>
  
  <pre><code>var json = JsonConvert.SerializeObject(payload);
  
  var client = new RestClient
  {
      Authority = "",
      Credentials = OAuthCredentials.ForProtectedResource(Registration.ClientKey, 
          Registration.ClientSecret, 
          AuthorizationToken.Token, 
          AuthorizationToken.Secret),
      Method = WebMethod.Post,
      Path = url
  };
  
  var request = new RestRequest();
  request.AddHeader("Accept", ContentType);
  request.AddHeader("Content-Type", ContentType);
  request.AddPostContent(Encoding.UTF8.GetBytes(json));
  
  response = client.Request(request);
  </code></pre>
  
  <p>I'm not having any trouble with authorization. I just kept getting a 400 error. After capturing the request with Fiddler, I noticed that content-length was 0. What am I missing? Do I need to do something in addition to AddPostContent? When I check the request object right before executing, there is content in PostContent, but it's as if Hammock isn't adding it to the request. I am using the latest full nuget (not ClientProfile).</p>
