LINQ3 Provider

~~~~~~~~~~~~~~

358-
LINQ syntax contains a positional operator (``$``) that you can use to update elements in an array field.
359-
Previous versions of the {+driver-short+} supported both the LINQ2 and LINQ3 providers.
360-
In LINQ2, you could use ``-1`` to indicate use of the positional operator.
361-
362-
For example, the ``Restaurant`` class contains an array field named ``Grades`` that
363-
contains multiple ``GradeEntry`` elements. If your application were using the LINQ2
364-
provider, you could use the following code sample to update the
365-
``Grade`` field of the first element in this array:
