How can I get Json.NET to deserialize into dynamic objects but still do reference resolution?
dynamic d=JsonConvert.DeserializeObject(...)

    The way I did it now is with a postprocessing step and a recursive function that's doing its own reference saving and rewiring:

        private static void Reffing(this IDictionary current, Action exchange,IDictionary refdic)
    {
        object value;
        if(current.TryGetValue("$ref", out value))
        {
            if(!refdic.TryGetValue((string) value, out value))
                throw new Exception("ref not found ");
            if (exchange != null)
                exchange(value);
            return;
        }
        if (current.TryGetValue("$id", out value))
        {
            refdic[(string) value] = current;
        }
        foreach (var kvp in current.ToList())
        {
            if (kvp.Key.StartsWith("$"))
                continue;
            var expandoObject = kvp.Value as ExpandoObject;
            if(expandoObject != null)
                Reffing(expandoObject,o => current[kvp.Key]=o,refdic);
            var list = kvp.Value as IList;
            if (list == null) continue;
            for (var i = 0; i < list.Count; i++)
            {
                var lEO = list[i] as ExpandoObject;
                if(lEO!=null)
                    Reffing(lEO,o => list[i]=o,refdic);
            }
        }
    }



    used as:
    


            var test = JsonConvert.DeserializeObject(...);
        var dictionary = new Dictionary();
        Reffing(test,null,dictionary);
