Inlining collections with EF Projection - entity-framework

Question

I have the following classes:
public class Customer {
public int Id {get;set;}
public string Name {get;set;}
public List<Order> Orders {get;set;}
//other attributes
}
public class Order{
public int Id {get;set;}
public string Name {get;set;}
public decimal Value {get;set;}
}
Given a customerId I wish to only select the customer name and the order Id using projection in EF.
I am doing the following:
IQueryable<Customer> customer = DataContextFactory.GetDataContext().Set<Customer>();
var tempCustomer = customer.Where(x => x.Id == customerId).Select( c=>
new
{
Name = c.Name
}
)
This gives me the customer name. Which I can then pass back to the entity like so:
var customerToReturn = tempCustomer.ToList().Select(x => new Customer
{ Name = x.Name});
If I include the order on the query like this:
var tempCustomer = customer.Where(x => x.Id == customerId).Select( c=>
new
{
Name = c.Name,
Orders = new {
Id = c.Orders.Id
}
}
)
Then I get a duplicate customer per order line (as per the SQL generated by EF). Is there a way I can inline this generation into a single SQL call?
Currently I am getting around this by calling each child object separately.
