> I have a .NET Core application that needs to publish AVRO JSON encoded messages to our Confluent Kafka REST API.  I can see that the Java and C++ API's have a JSON encoder, but I couldn't tell from the documentation whether the C# API has it, or at least it doesn't seem to.  The documentation for the C# API is a little light on for details.  The Kafka REST API supports JSON, and AVRO JSON, but not binary AVRO from what I understand.
> The main problem facing the plain JSON we are currently publishing is that when using an AVRO schema and the union type, we hit the problem described here https://issues.apache.org/jira/browse/AVRO-2899.  We need to generate the type information in the JSON in order to satisfy the validation in the Kafka REST API.  Hence, the need for an AVRO JSON encoder.
> I can't re-write the .NET application, so I'm faced with the prospect of using either the Java or C++ API's with some sort of wrappers or interoperability framework, which I'm desperately trying to avoid.
> Any assistance or suggestions would be much appreciated.
