Json.net Does Not Call Custom ContractResolver for Custom Excetion

Question

I need to pass information about custom exception types from the WebApi web service to the client. To do this, I'm trying to use the Json.Net + CustomContractResolver serializer to control what is sent to the client.

public class Data //: Exception
{
    public string Prop1 { get; set; }
    public string Prop2 { get; set; }

    public Data()
    {
        Prop1 = "Hi";
        Prop2 = "Bye";
    }
}

public class CustomContractResolver : DefaultContractResolver
{
    // !!! Method is not being invoked if Data is inherited from Exception
    protected override JsonProperty CreateProperty(MemberInfo member, MemberSerialization memberSerialization)
    {
        JsonProperty property = base.CreateProperty(member, memberSerialization);
        property.ShouldSerialize = instance => property.PropertyName == "Prop1";
        return property;
    }
}

class Program
{
    static void Main(string[] args)
    {
        var settings = new JsonSerializerSettings 
                           {
                               ContractResolver = new CustomContractResolver() 
                           };
        string json = JsonConvert.SerializeObject(new Data(), settings);

        Console.WriteLine(json);
        Console.ReadLine();
    }
}

I tried to run this code using Json.Net 6.0.4 and 6.0.6. Used .Net Framework 4.5.0 and 4.5.2. But the problem is the same - when the data is inherited from Exception CustomContractResolver does not work (nuget configuration line: package id = "Newtonsoft.Json" version = "6.0.6" targetFramework = "net45" or package id = "Newtonsoft.Json" version = "6.0.6" targetFramework = "net452")

, UnitTest (xUnit.Net), PCL .Net 4.5.0 ( nuget: package id = "Newtonsoft.Json" version = "6.0.6" targetFramework = "portable-net45 + win + wpa81 + MonoAndroid10 + MonoTouch10" ).

- , , Json?

:

ContractResolver = new CustomContractResolver { IgnoreSerializableInterface = true, IgnoreSerializableAttribute = true };
