Hi Dragan, nfJson can serialize the most complex object,
even objects with two dimensional arrays containing objects,
and collections containing collections and arrays.

Regarding type conversion, it is done automatically ( except for
specific numeric values like double, float or money , -wich btw are
rarely used - they'll pass as numeric )

I don't know why there's this specific need for passing an
object as value, but this is the only solution, and there's no
significant performance penalty involved, ( unless you
serialize objects with a high resulting string size )
