为什么我的WCF服务在返回自定义对象时有问题

所以我的问题很像这个:WCF服务:返回自定义对象，然而，尽管在这个问题的解决方案，我看到没有工作。

昨天我提出了一个与此相关的问题，但我已经接近了，如果没有确定我的问题的潜在根源。

我不认为这是我正在处理的数据大小的问题。我可以将此数据发送到服务器，但我有检索它的问题。我返回一个对象叫ProjectDetails/WCF。然而，我遇到了从服务接收到客户端的问题。

是否有一个设置，我缺少或有一种方式我配置我的类为WCF不正确?

这是我的ProjectDetails代码:

[DataContract]
public class ProjectDetails 
{
    [DataMember]
    public int projectId { get; set; }
    [DataMember]
    public string name { get; set; }
    [DataMember]
    public int calYearId { get; set; }
    [DataMember]
    public string projectState { get; set; }
    [DataMember]
    public string reportTitle { get; set; }
    [DataMember]
    public int plantId { get; set; }
    [DataMember]
    public string holdNumber { get; set; }
    [DataMember]
    public string holdDescription { get; set; }
    [DataMember]
    public string remarks { get; set; }
    [DataMember]
    public string adminComments {get; set; }
    [DataMember]
    public int companyId { get; set; }
    [DataMember]
    public int customerId { get; set; }
    [DataMember]
    public string folderNumber { get;  set; }
    [DataMember]
    public int invoicedInFull { get; set; }
    [DataMember]
    public int approved { get; set; }
}

在我的服务契约中是这样定义的:

[ServiceContract]
public interface IProjectService
{
    [OperationContract]
    ProjectDetails GetProjectDetails(int selected_id);
}

我已经用svcutil.exe重新生成了我的代理并更新了我的服务引用。然而，每次我调用GetProjectDetails方法时，我的代码都会失败。我得到:

底层连接已关闭:接收时发生意外错误。

如果有人能帮忙，我将非常感激。
