Welcome! In this unit, we will explore how to implement Pub/Sub (publish/subscribe) for notifications within our Redis-based backend system project using C#. You've already learned how to manage user data, handle transactions with pipelines, and track activities with event logs. Now, we're going to add another powerful feature to our project: real-time notifications using Redis Pub/Sub with C#. This will enable our system to send and receive messages instantaneously.

In this unit, we'll focus on creating a simple real-time notification system using Redis Pub/Sub in C#. Specifically, we'll cover:

1. Publishing Messages: How to send notifications using C#.
2. Subscribing to Channels: How to receive and handle notifications with the appropriate libraries in C#.

Here is a quick refresher on how Pub/Sub works in Redis using C#:
