@Tobias, This is not an answer. But since it was a little bit long for comment, I post it here. Maybe it can help to diagnose your problem. [A full working code].

public void TestWCFService()
{
    //Start Server
    Task.Factory.StartNew(
        (_) =>{
            Uri baseAddress = new Uri("http://localhost:8080/Test");
            WebServiceHost host = new WebServiceHost(typeof(TestService), baseAddress);
            host.Open();
        },null,TaskCreationOptions.LongRunning).Wait();


    //Client
    var jsonString = new JavaScriptSerializer().Serialize(new { xaction = new { Imei = "121212", FileName = "Finger.NST" } });
    WebClient wc = new WebClient();
    wc.Headers.Add("Content-Type", "application/json");
    var result = wc.UploadString("http://localhost:8080/Test/Hello", jsonString);
}

[ServiceContract]
public class TestService
{
    [OperationContract]
    [WebInvoke(RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.Wrapped)]
    public User Hello(Transaction xaction)
    {
        return new User() { Id = 1, Name = "Joe", Xaction = xaction };
    }

    public class User
    {
        public int Id { get; set; }
        public string Name { get; set; }
        public Transaction Xaction { get; set; }
    }

    public class Transaction
    {
        public string Imei { get; set; }
        public string FileName { get; set; }
    }
}
