title: TransactionScope has aborted transaction before disposal
body: <p>When using TransactionScope it apperars that if internally executed code rolled back the transaction than the parent transaction will rollback as well. Which is good for me. But when disposing that scope it throws an exception meaning that transaction was rolled back already and aborted. 
  So what is the right way to handle that and properly dispose the scope?</p>
  
  <pre><code>    using (TransactionScope scope = new TransactionScope(TransactionScopeOption.RequiresNew))
      {
                      using (var conn = GetConnection())
                      {
                              string query = 
                @"some query that may contain transaction itself 
                or some SP whith transaction included"
  
                              using (var command = new SqlCommand(query, conn))
                                  command.ExecuteNonQuery();
                          }
                      }
                      scope.Complete();
      } // Exception here
  </code></pre>
