Dear all, this is my scenario:

1. on my Ms.Sql Server the timeout is set for 10 minutes (see the link)

2. in my code I have this transaction where the timeout is set for 20 minutues

using (TransactionScope ts = new TransactionScope(TransactionScopeOption.Required, new System.TimeSpan(0, 20, 0)))
{
    //bla.. bla... bla...
    ts.Complete();
    return true;
}    

What I have tried:

My question is: between the 2 settings which one will be considered and executed?
The server timeout or code timeout.

Best regards
