If you build the edmx file from the database and then the db changes, how do you get the model to pick up the change?
Do you delete the whole model and regenerate or can you detect changes?
I see a post mentioning a "Update Your Model" rt. mouse command on the edmx file, but I dont see it.
Updating your edmx to reflect changes made in your db (.net linq-to-entities)
I'm just starting out.

Right-click anywhere on the design surface, and select Update Model from Database. In the Update Wizard, select the Refresh tab and then select Tables > dbo > Student. Click Finish. After the update process is finished, the database diagram includes the new MiddleName property.
Update the .edmx file when the Database changes In the Model Browser, right-click the . edmx file and select Update Model from Database. Expand the Tables, Views, and Stored Procedures nodes, and check the objects you want to add to the . edmx file.
Update Objects in Entity Framework 4.0First retrieve an instance of the entity from the EntitySet<T> (in our case ObjectSet<Customer>), then edit the properties of the Entity and finally call SaveChanges() on the context.
Are you looking at the designer or code view? You can force the designer to open by right clicking on your EDMX file and selecting Open With -> ADO.NET Entity Data Model Designer
Right click on the designer surface of the EDMX designer and click Update Model From Database...
All entities are refreshed by default, new entities are only added if you select them.
EDIT: If it is not refreshing well.
