Azure ServiceBus上的SqlFilter主題訂閱沒有過濾

我有一個WinRT應用程序，我正在使用Windows Azure Toolkit for Windows 8。我有一個設置，我希望客戶訂閱忽略發佈到ServiceBus主題的消息，如果他們是發件人或者消息比訂閱開始時更早。Azure ServiceBus上的SqlFilter主題訂閱沒有過濾

在我BrokeredMessage的屬性，我已經添加了2項涵蓋了這些情況：

message.Properties["Timestamp"] = DateTime.UtcNow.ToFileTime(); 
message.Properties["OriginatorId"] = clientId.ToString();

的clientId是一個GUID。

用戶側看起來是這樣的：

// ti is a class that contains a Topic, Subscription and a bool as a cancel flag. 

string FilterName = "NotMineNewOnly"; 

// Find or create the topic. 
if (await Topic.ExistsAsync(DocumentId.ToString(), TokenProvider)) 
{ 
    ti.Topic = await Topic.GetAsync(DocumentId.ToString(), TokenProvider); 
} 
else 
{ 
    ti.Topic = await Topic.CreateAsync(DocumentId.ToString(), TokenProvider); 
} 

// Find or create this client's subscription to the board. 
if (await ti.Topic.Subscriptions.ExistsAsync(ClientSettings.Id.ToString())) 
{ 
    ti.Subscription = await ti.Topic.Subscriptions.GetAsync(ClientSettings.Id.ToString()); 
} 
else 
{ 
    ti.Subscription = await ti.Topic.Subscriptions.AddAsync(ClientSettings.Id.ToString()); 
} 

// Find or create the subscription filter. 
if (!await ti.Subscription.Rules.ExistsAsync(FilterName)) 
{ 
    // Want to ignore messages generated by this client and ignore any that are older than Timestamp. 
    await ti.Subscription.Rules.AddAsync(FilterName, sqlFilterExpression: string.Format("(OriginatorId != '{0}') AND (Timestamp > {1})", ClientSettings.Id, DateTime.UtcNow.ToFileTime())); 
} 

ti.CancelFlag = false; 

Topics[boardId] = ti; 

while (!ti.CancelFlag) 
{ 
    BrokeredMessage message = await ti.Subscription.ReceiveAndDeleteAsync(TimeSpan.FromSeconds(30)); 

    if (!ti.CancelFlag && message != null) 
    { 
     // Everything gets here! :(
    }

我回來的一切 - 所以我不知道我做錯了。解決訂閱過濾器問題的最簡單方法是什麼？
