VS 2008 ADO.NET Entity Data Model questions

I am learning L2E and have two questions:

1. when I add ADO.NET Entity Data Model to my VS 2008 C# project. VS will add a cs file for you and the default namespace will be your project name, saying SystemSoftware in my case. Can I config VS to create a different namespace, such as MyCompany.SystemSoftware, for me or I have to manually change them? If VS can do it for me, please tell me how to setup the VS.

2. how to update the Entity Data Model if my database tables changed? or I have to remove the Model and recreate again?

thanks,

• found answers to my questions:

  1. right click the .edmx entry and select the Properties. In the Properties window, put your namespace into Custom Tool Namespace entry and rebuild, done

  2. double click the .edmx entry, the Updata Model Wizard will show up (like a ER diagram), right click on it, select Update Model from Database ..., done.
