System.Runtime.Serialization.Serialization异常:应为命名空间中的元素

出于某种原因，我觉得这个对post的调用设置不正确，这意味着我收到的消息是WCF中的方法没有在post中接收InventoryRequest对象？

   var inventoryRequest = new InventoryRequest
    {
        memberID = "1",
        Inventories = _inventories.ToArray()
    };

    //Act
    using (var client = new HttpClient())
    {
        client.BaseAddress = new Uri("http://localhost/Inventory");
        client.DefaultRequestHeaders.Accept.Clear();
        client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
        inventoryResponse = await client.PostAsJsonAsync("", inventoryRequest).Result.Content.ReadAsAsync<InventoryResponse>();
    }

我在MSTest中收到此错误：

    System.Runtime.Serialization.SerializationException: Error in line 1 position 70. Expecting element 'InventoryResponse' from namespace 'http://schemas.datacontract.org/2004/07/Responses'.. Encountered 'Element'  with name 
'Fault', namespace 'http://schemas.microsoft.com/ws/2005/05/envelope/none'.

   at System.Runtime.Serialization.XmlObjectSerializer.ReadObjectHandleExceptions(XmlReaderDelegator reader, Boolean verifyObjectName, DataContractResolver dataContractResolver)
   at System.Runtime.Serialization.DataContractSerializer.ReadObject(XmlReader reader)

同样奇怪的是，它在谈论上面的xml阅读器。我指定json作为内容类型，那么它为什么要尝试使用xml进行解析呢？

旁注：当我在Fiddler中尝试对同一个uri执行POST并在Fiddler主体中指定InventoryRequest的json表示时，它工作得很好。。。并返回json

以这种方式尝试：

using (var client = new HttpClient())
{
    client.BaseAddress = new Uri("http://localhost/");
    client.DefaultRequestHeaders.Accept.Clear();
    client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
    inventoryResponse = await client.PostAsJsonAsync("Inventory", inventoryRequest).Result.Content.ReadAsAsync<InventoryResponse>();
}
