难以在与服务相同的解决方案中调用在本地主机上运行的 WCF POST 服务

我在开发和测试接收和返回 JSON 的 POST Web 服务时遇到问题。我正在通过从同一测试项目中的表单调用它来测试它(或尝试/想要测试它(解决方案即 Web 服务。但是，似乎无论我做什么，我都会收到"错误请求"，或者调用服务时出现"未找到"错误。

网络上有很多关于这些事情的帖子，一般是WCF，有例子等，但我似乎无法解决问题，这非常令人沮丧：-((。

我正在使用VS 2010(不要笑(赢得XP。但是我不明白为什么过时的操作系统应该很重要。

单个方法的签名是

public Stream ReceiveCardStatusInfo(Stream request)

我已经通过 svcutil 生成了一个代理，但我没有使用它。我尝试将网络服务项目引用为普通引用和服务引用(当前为服务引用(。项目的属性是几乎是默认值，但在尝试解决问题时，WS 项目的网页当前显示"使用 Visual Studio 开发服务器"，选择"特定端口"，端口号 1318。(虚拟路径是默认值"/"(。

由于我不太确定问题到底是什么，所以我提供了我所有的代码和配置文件;表单的逻辑首先(用于调用服务(和该项目的 app.config，以及服务以下组件：

表格1：

public Form1() {
  InitializeComponent();
}
public void button1_Click(object sender, EventArgs e) {
  var request = (HttpWebRequest)WebRequest.Create("http://localhost:1318/ReceiveData.svc/ReceiveCardStatusInfo"); // /ReceiveCardStatusInfo
  request.ContentType = "text/json";
  request.Method = "POST";
  string json = new JavaScriptSerializer().Serialize(new {
    AuthenticationToken = "...",
    Campus = "Te Awamutu",
    StudentID = "200122327",
    EnrolmentEndDate = "11/06/2015",
    CardStatus = "Suspended",
    SuspendedDate = "18/08/2014",
    OrderedDate = "20/09/2014",
    ReprintDate = "07/10/2014"
  });
  using (var sW = new StreamWriter(request.GetRequestStream())) {
    sW.Write(json);
    sW.Flush();
    sW.Close();
  }
  var response = (HttpWebResponse)request.GetResponse();
  string result;
  using (var streamReader = new StreamReader(response.GetResponseStream())) {
    result = streamReader.ReadToEnd();
  }
  MessageBox.Show(result);
}

app.config(我不太明白这个文件中需要什么，但我很难找到一个对此有明确的答案，因此它包含它的作用(：
