📝 Walkthrough

Walkthrough

This PR implements a complete Orders service microservice with domain-driven design, EF Core persistence on PostgreSQL, transactional order placement with outbox messaging, and integration tests. Changes include domain models, database schema and migrations, a feature handler, full service wiring, and validation of the atomic persist-and-enqueue workflow.

Changes

Orders Service Implementation

Layer / File(s)	Summary
Project Dependencies & Tooling .config/dotnet-tools.json, .editorconfig, Directory.Packages.props, src/BuildingBlocks/Persistence/BuildingBlocks.Persistence.csproj, src/Services/Orders/Services.Orders.csproj, tests/Integration/Tests.Integration.csproj	Added dotnet-ef tool manifest pinned to 10.0.8, exempted migration files from style rules, downgraded EF Core packages from 10.0.8 to 10.0.4 (for Npgsql alignment), and added EF Core and PostgreSQL dependencies across project files.
Order Domain Model src/Services/Orders/Domain/Order.cs	Defined OrderStatus enum with Pending, Confirmed, Cancelled states and sealed Order aggregate with validated Place() factory, immutable properties, and Confirm()/Cancel() state transitions.
Database Schema & EF Core Mapping src/Services/Orders/Infrastructure/OrderConfiguration.cs, src/Services/Orders/Infrastructure/OrdersDbContext.cs, src/Services/Orders/Infrastructure/OrdersDbContextFactory.cs, src/Services/Orders/Migrations/*	Created EF Core entity configuration mapping Order to orders table, implemented OrdersDbContext with orders schema and outbox/inbox inheritance, added design-time factory, and generated migrations defining inbox, outbox, and orders tables with filtered outbox index.
Order Placement Feature Handler src/Services/Orders/Features/PlaceOrder.cs	Implemented PlaceOrderHandler that validates PlaceOrderRequest, creates a pending Order via the domain factory, persists it with OrdersDbContext, enqueues OrderPlaced integration event to IOutbox, and returns the new order ID in a single atomic SaveChangesAsync call.
Service Startup & Configuration src/Services/Orders/Program.cs, src/Services/Orders/appsettings.json	Configured OrdersDbContext with PostgreSQL connection, mapped MessagingDbContext for shared outbox unit-of-work, enabled outbox/inbox with RabbitMQ publisher and dispatcher, registered TimeProvider.System and PlaceOrderHandler, applied migrations at startup, and wired POST /orders endpoint to invoke the handler and return 201 Created.
Integration Test Suite tests/Integration/PlaceOrderTests.cs	Added integration test using Testcontainers PostgreSQL 17 container, validates that PlaceOrderHandler atomically persists a pending order and writes an unprocessed OrderPlaced outbox entry in a single transaction, including assertions on order state and outbox payload.

Poem

🐰 Hops with joy – Orders now bloom!
A domain dance in the database room,
Pending state begins its tale,
Outbox enqueues without fail.
Migrations set the schema stage – tests prevail! ✨
