c# - Entity Framework Working with temporary objects -

i'm using ef 4.1 , want perform checks using temporary objects.

the problem i've encountered is, objects written database save changes. tried detach objects, whole object graph gets shredded , can't access referenced objects required checks.

my code looks this:

createtemporder() {     order order = new order();     order.customer = dbcontext.customers.single(c => c.id == cid);     dbcontext.detach(order);     return order; } 

are there best practices handle temporary objects in ef or need override detachment procedure?

thanks in advance

if don't want ef track entities can use asnotracking() method:

order = dbcontext.orders.asnotracking().single(o => o.id == oid); 

of course works if order entity managed ef.
