.NET 8 Microservices with RabbitMQ and MassTransit

Set up the solution and folder structure in Visual Studio 2022, creating building blocks, common and contracts folders, and four microservice projects for flight, booking, payment, and notification.

Connect all four microservices to a single airline booking system database, create and seed four tables—bookings, flights, notifications, payments—with defined fields, and validate basic CRUD operations in SQL Server 2022.

Define repository interfaces for microservices in a clean architecture, decoupling core entities from data stores and APIs. Implement IBookingRepository, IFlightRepository, INotificationRepository, and IPaymentRepository with async methods.

Set up the booking repository in the infrastructure layer using a SQL connection and dapper, wiring up appsettings connection strings and IDbConnection for async operations.

Connect the flight infrastructure by wiring the shared SQL connection in appsettings and program.cs, implement the flight repository with Dapper, and enable flight add, delete, and query operations.

Rename the controller to notifications controller, set the api/notifications route, remove weather forecast code, implement post endpoint sending a notification via mediator with a from body command and return ok.

Set up building blocks for inter-service communication with RabbitMQ and MassTransit by creating queues for flight booked, payment processed, and notification, and defining event contracts as records.

Install Docker Desktop and run a RedisAI container locally to cache booking data, connect via RedisAI insight, and create booking keys prefixed with booking_ for the refactored booking microservice.
