    Remarks
    Hints are used declaratively. They tell LiveLinq query optimizer to create and use an index on that column, if possible. When the query is executed, the hint method IndexedField is replaced with the standard LINQ to DataSet extension method Field. See C1.LiveLinq.Hints for more details.
    Example
    var query = from c in customersTable
    where c.IndexedField<string>(customerColumn) == "ALFKI"
    select c;
