自訂 AdventureWorks .edmx 檔案 (Entity Framework)。
本範例是以 AdventureWorks 資料模型為基礎，該資料模型將 Contact、SalesOrderHeader 和 SalesOrderDetail 資料表對應至 Contact、Orders 和 LineItem 型別。 您不必依照定義此模型之步驟 (描述在 HOW TO：自訂模型與對應檔以搭配自訂物件運作 (Entity Framework) 中) 執行，可以建立空的模型再於編輯器中編輯模型。 若要編輯模型，請開啟 AdventureWorksModel.edmx 檔案，再複製 edmx:Runtime 標記間的下列程式碼。
