This project's aim is to provide a simple interface to broadcast messages within the local network by using UDP. Just in case you can't do any Zeroconf, UPnP, PGM, or message queuing with publish semantics to register and publish services with zero to none configuration effort.

IMessageFactory You can inject your own IMessageFactory implementation, to send eg CustomMessage instances instead to default Message.

IMessageSerializer Instead of using the default BinaryFormatter as the serializer of IMessage instances, you can provide your own serialization mechanism.

IMessageBodySerializer Instead of using the default BinaryFormatter as the serializer of IMessage.Body, you can provide your own serialization mechanism.

IPathFactory If you ever come across the need to adapt routing from the default Type.FullName of the encapsulated instance, you can provider your own implementation.

csharp-UDPBroadcast is published under WTFNMFPLv3.

While implementing this project, I listened to this playlist. If you want to make adaptions to the project, I strongly recommend listening to this playlist, as it gets you in the right mood.
