Basically, this project would follow the same paradigm of [rocketmq-client-cpp v5.0.0](https://github.com/apache/rocketmq-client-cpp/tree/main). Namely, we would build the whole client following protocols described in [rocketmq-apis](https://github.com/apache/rocketmq-apis) on top of [gRPC-dotnet](https://github.com/grpc/grpc-dotnet), utilizing [Protocol buffers](https://developers.google.com/protocol-buffers) to serialize and deserialize data in transmission.
