You should be able to do

mqttMessageBuilder
  .WithPayload(protoObject.ToByteArray())
  .WithContentType("application/vnd.google.protobuf")

and put that in an extension method if you prefer.

On the receiving side, just look for the content type and do

ExpectedType.Parser.ParseFrom(msg.Payload)

FWIW I would not expect the string encoding to work as you seem to assume.

You can also take a look at https://github.com/SeppPenner/SparkplugNet which uses ProtoBuf messages over MQTT.
