9/3/2023 0 Comments SerializationIn these cases, the endpoint will automatically try to load the specified message type at runtime. Incoming messages might refer to a message type that has not yet been loaded by the endpoint. To avoid unintended behavior during message deserialization, avoid executing code with side effects as part of constructors and property setters of message types. Although NServiceBus only deserializes message payloads that are considered a valid message type, side effects in constructor methods or property setters of message contracts may be abused by an attacker with access to the transport infrastructure. The deserialization target type is defined by the incoming message. The serializer and Newtonsoft JSON Serializer by default support immutable messages types. When messages are in serialized form "on the wire" it makes no difference if mutable or immutable message types are used. NServiceBus does not restrict this It depends on the chosen serializer implementation if it supports deserializing to non public properties and/or using non-default constructors to initialize types. It is possible to use immutable types as messages. When using multiple deserializers make sure that there's only one type registered per given ContentType. Unless explicitly configured otherwise, NServiceBus will use XmlSerializer for serializing and deserializing all messages. The default serializer used in NServiceBus projects is the custom XmlSerializer. The same serializer must be used by the sending endpoint to serialize messages and by the receiving endpoint to deserialize them, unless additional deserializers are specified. Refer to the dedicated documentation pages for each available serializer for more information about the specific configuration. Supported serializersĪ serializer can be configured using the endpointConfiguration. Other serializers are supported in order to enable specific performance or integration requirements. JSON provides a good combination of compactness, human readability, and performance. The serializer provides an effective general-purpose serializer appropriate for most use cases based on the JSON serialization built into. This way, messages serialized before the transition (including saga timeouts and delayed messages) can still be understood while new messages use the new serializer. In a global landscape of constantly evolving regulatory, market, and technical requirements, serialization is, and will likely remain, a complex topic for all industry actors. This is accomplished by adding the previous serialization format as an additional deserializer, which is supported in NServiceBus versions 6 and above. Serialization is one of the biggest information technology (IT) challenges to affect the pharmaceutical sector in the last decade. It's possible to transition to another serialization format while still remaining compatible with messages in-flight that used the previous serialization format. NServiceBus achieves this using serializers. As part of this process, the object must be serialized and deserialized. NET objects (messages, events, and commands) and sends/receives them over a specified transport. This article is part of the NServiceBus Learning Path.
