WCF 5.0和Firebird .NET提供：$展開破

Question

以下（WCF 5.0 & DevArt提供商）的鏈接描述的問題似乎也適用火鳥.NET提供：

http://social.msdn.microsoft.com/Forums/en/adodotnetdataservices/thread/e74ea4d1-a262-4326-8529-c146a3acfb6d

然而我已經試過5.1.0-pre版本，仍然得到ArumentNullException：值不能爲空。參數名稱：值。

除此之外，行爲與描述完全相同。不過，它確實在WCF 5.0 CTP中工作。

任何人都可以確認這是WCF 5.0 RC或Firebird .NET Provider中的錯誤嗎？有沒有解決辦法，還是必須降級到CTP？

這是調用堆棧：

5.1.0-RC版本還修復了問題火鳥提供商。正如Vitek Karas提到的，我忘了從GAC中刪除5.0 RTM。所以我從來沒有真正嘗試過5.1.0-rc。
