Windows 10 Inter Process Communication Pub/Sub hub

Inter Process Communication pub sub hub I need a way for different processes running on a Windows 10 computer to pass data to one another. I would like this to be in the form of a windows service that implements the publish/subscribe pattern. This service would run in the background. Processes running on the system would be able to publish data objects to the service. After an object was published the pubsub service would hold a copy of the object in memory, and attach an “address” (string) to the object that other processes can use to reference it. Processes running on the system would be able to subscribe to objects that were published to the pubsub service. After subscribing to an object, a process would be updated by the pubsub service when the object changed. Prefer a named pipe implementation, but open to suggestions. Python preferred, but C# is fine too.
