it seems like the error is occurring when attempting to use the DynamicMethod constructor in the System.Reflection.Emit namespace, which is not supported on certain platforms, such as iOS and some versions of Linux

You can overload WatsonTcpClient.SerializationHelper and WatsonTcpServer.SerializationHelper with your own implementation using Newtonsoft.Json (or other preferred serializer) using the ISerializationHelper interface.
