Json.Net adding $id to EF objects despite setting PreserveReferencesHandling to “None”

by

The custom ContractResolver setting overrides the PreserveReferencesHandling setting.

In your implementation of DefaultContractResolver/IContractResolver, add this;

public override JsonContract ResolveContract(Type type) {
    var contract = base.ResolveContract(type);
    contract.IsReference = false;
    return contract;
}

This behaves similarly to the PreserveReferencesHandling.None setting without a custom ContractResolver.
