Linq to SQL vs實體數據模型：獲取存儲過程運行

我以前是否在使用Silverlight和RIA，我使用的是ADO.NET實體數據模型和域上下文。我正在教自己如何從RIA運行一個存儲過程，並且無法使它與之前的設置一起工作，因此我開始嘗試使用LINQ to SQL方法。我做了以下內容：Linq to SQL vs實體數據模型：獲取存儲過程運行

新增的DBML
拖動和放棄我的表和示例存儲過程
保存的DBML和建成並重建解決方案和項目文件。
創建一個域服務並嘗試添加dbml。

這裏是我的DBML alt text

這是我的錯誤。 可用的DataContext/ObjectContext類列表顯示爲空。我已經重建了很多次，甚至重新開始了視覺工作室。 alt text

因此，這裏是我的問題：

有沒有一種簡單的方法做ADO.Net我失蹤therfore我可以跳過添加LINQtoSQL類存儲過程。
我錯過了一些非常簡單的方法來添加dbml類並添加一個存儲過程。
