> Hi,
> I am working on a .NET/C# project that uses Kafka with Avro
> serialization/deserialization in an event streaming platform.
> .NET Apache.Avro nuget package contains two different set of classes for
> serialization/deserialization: - SpecificReader, SpecificWriter -
> ReflectReader, ReflectWriter. We have chosen ReflectReader/Writer
> ([https://avro.apache.org/docs/current/api/csharp/html/md_src_apache_main_Reflect_README.html])
> so we can use POCO classes to represent a message.
> I noticed that ReflectReader/Writer does not support LogicalSchema. There are
> default converters and Avro field attribute instead (they are extendable and
> flexible).
> My questions are:
> * is it intentional to not support LogicalSchema for ReflectReader/Writer?
> * does it mean that we should not mix services that use LogicalSchema (third
> party or just written on Java, Phyton or other languages) with ones that use
> ReflectReader/Writer?
>
> Thanks,
> Khrystyna
