------------------------------------

             Summary: Request for C# API to implement a JSON Encoder
                 Key: AVRO-3274
                 URL: https://issues.apache.org/jira/browse/AVRO-3274
             Project: Apache Avro
          Issue Type: Improvement
          Components: csharp
    Affects Versions: 1.10.2
            Reporter: Andrew Benedek


This is a request or improvement.

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 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.
