title: What is the default ADO.NET isolation level?
body: <p>I know that if I use <code>System.Transactions.TransactionScope</code> and don't specify an isolation level, it will default to <code>Serializable</code>. However, what if I'm not using transaction scope, and am just using an old-fashioned table adapter? What is the default isolation level then?</p>
  
  <p>Many thanks in advance.</p>
