Reservation Service

This is a Reservation Service built with ASP.NET Core 9, designed to handle room bookings efficiently and prevent duplicate or conflicting reservations.

The project uses Vertical Slice Architecture to achieve better separation of concerns and maintainability.
To handle concurrency and avoid race conditions, it leverages Redis and RedLock.net for distributed locking to handle concurrency and prevent double booking scenario.
It also implements the Outbox Pattern to ensure reliable and consistent delivery of notification messages to RabbitMQ, enabling eventual consistency in a distributed environment.
