Conflicting field IDs error in Ignite C# thin client

Question

I am trying to store entity in a Ignite-Cache using C# thin client. I have below scenario

public class A
    {
        DateTime StartDate { get; set; }
    }

    public class B:A
    {
        DateTime StartDate { get; set; }
    }

When i am trying to store instance object of class B in ignite store it give me below error.

IgniteThinClient.GetCache<Tkey, TValue>("CacheName")

It gives me below error

Apache.Ignite.Core.Binary.BinaryObjectException: 'Conflicting field IDs [type=B, field1=StartDate , field2=StartDate , fieldId=104069929]'

How can I turn off binary object storing for C# thin client? Will that will help to resolve this issue?

Are you sure that you want to have a class hierarchy like this? Usually this is a result of a mistake: either use `override` or `new` for a property with the same name in the derived class. — Pavel Tupitsyn, Sep 30 '19 at 08:10
Even though I will use new or override for a property. It is still give same error. — Gopu_Tunas, Oct 01 '19 at 10:46

Please check out docs on serialization. You could try to implement IBinarizable in B, and only write the field that you care about (or put both under differing names). Your mileage may vary.

Is there other way to do this as I have huge number of entities with above issue? – Gopu_Tunas Oct 01 '19 at 10:47
Or is there any Ignore attribute for ignoring property? – Gopu_Tunas Oct 01 '19 at 11:34

I think you can try mark these properties with `[NotSerialized]`. Can you try that? – alamar Oct 01 '19 at 11:48
