  1. C# keywords supporting LINQ are still C#. Consider where as a conditional like if; you perform logical operations in the same way. In this case, a logical-OR, you use ||

    (from creditCard in AvailableCreditCards   where creditCard.BillToName.ToLowerInvariant().Contains(              txtFilter.Text.ToLowerInvariant())    || creditCard.CardNumber.().Contains(txtFilter.Text)  orderby creditCard.BillToName  select creditCard)
