推荐答案

Hello Lisa，

否，使用Visual Studio 2010 beta 2，您现在可以单击图中的关联，您将看到"End1 OnDelete"。和"End2 OnDelete"和"End2 OnDelete"属性窗格中的属性。

希望这有帮助，

Hello Lisa,

No, using Visual Studio 2010 beta 2, you can now click on an association in the diagram, and you will see "End1 OnDelete" and "End2 OnDelete" properties in the properties pane.

Hope this helps,
Diego
