TransactionScope Prematurely Completed

Don’t forget to supress your select statements from your TransactionScope. In SQL Server 2005 and above, even when you use with(nolock), locks are still created on those tables the select touches. Check this out, it shows you how to setup and use TransactionScope.

using(TransactionScope ts = new TransactionScope 
{ 
  // db calls here are in the transaction 
  using(TransactionScope tsSuppressed = new TransactionScope (TransactionScopeOption.Suppress)) 
  { 
    // all db calls here are now not in the transaction 
  } 
}
