Newtonsoft.json: Option to ignore empty collections

[ejsmith]

I would like to have a serializer option to ignore empty collections. Right now I am using this:

I think this is something people can add themselves like you have do or with a JsonConverter.

By default Json.NET serializers through the IEnumerable interface, which makes it difficult to determine whether a collection is empty or not.

Yeah, that is why I am just checking for a Count property and using that if it exists. You have fast reflection code so this should be pretty cheap. I feel like this is a pretty core thing that would be nice to be included in the core serializer.
