using System.Transactions;

using (TransactionScope scope = new TransactionScope())
{
    try
    {
        using(DataContext contextObject = new DataContext(ConnectionString))
        {
            contextObject.Connection.Open();
            // First SaveChange method.
            contextObject.SaveChanges();

            // Second SaveChange method.
            contextObject.SaveChanges();
            //--continue to nth save changes

            // If all execution successful
            scope.Complete();   
       }
    }
    catch(Exception ex)
    {
        // If any exception is caught, roll back the entire transaction and end the scope.
        scope.Dispose();
    }
    finally
    {
        // Close the opened connection
        if (contextObject.Connection.State == ConnectionState.Open)
        {
            contextObject.Connection.Close();
        }
    }
}
