    I am using JSON.NET to deserialize objects that I want to reattach to the context. It works for a single entity without any references, but when I deserialize an entity that has references, AttachCopy fails on a NullReferenceException.

    Any guidance on that kind of scenario?

    Hello Alexis,

    please be a bit more specific: We would need to see the objects graph that comes back from the JSON deserialization. At the moment I guess, that the referenced entities are either not passed back, hence are null or that there are duplicate references to the same instance. But I cannot give a definitive answer until we have a reproduction of the issue. Can you provide us (through support) with one?

    Kind regards,
