Dear all

I am new commer for Json.net. I try to generally remove attribute created by ER framework during serialisation of ER object such as $id , EntityKey by JsonConverter. I consider JsonIgnore property before but seems not to apply object which is created by ER frame
How can I set this by JsonConverter?
