Entity Framework ( Entity travelled from EntityObject to DTO and then again to EntityObject ) is it possible to easily update it in db at this point ?

Question

Hello Everyone !

i think my whole questions is inside title bar =] but i'll explain little more.

i've got 2 related tables in database ( Customers and Orders ) and wcf service which returns Customer and all related Orders as DTO's like this :

class CustomerDto
{
int ID;
IList< OrderDto > Orders;
}
and :
class OrderDto
{
int ID;
string someString;
}

what is happening:
client asks for customer (customer is returned with orders ), makes some changes (adds/removes orders, changes someString), and sent data back to service.

here i wanted to ask, is it possible to attach modified Customer to database context, or i'll need make changes manually?

Thank You !

Here's an article with downloadable code sample on using EF and WCF together, including updates. You can also look at RIA services.
