## Overview

This repository is an ASP.NET Core order-management API for orders, order items, and products. Clients call the corresponding controllers, which delegate CRUD work to a shared repository backed by Entity Framework Core and SQLite. At startup, the application configures the database and seeds initial records. The tree also indicates saga, gateway, and event-hub concerns, but the sampled code does not establish how they connect to the API; the visible order-service gateway method is a stub.

Main entry points: [`ECommerce.Orders/Data/Context/OrdersDb/OrdersDbContext.cs`](https://github.com/bhavinpandya84/ecommerceproject/blob/master/ECommerce.Orders/Data/Context/OrdersDb/OrdersDbContext.cs) (EF Context), [`ECommerce.Orders/Data/Repositories/OrderRepository.cs`](https://github.com/bhavinpandya84/ecommerceproject/blob/master/ECommerce.Orders/Data/Repositories/OrderRepository.cs) (Order Repository), [`ECommerce.Orders/Program.cs`](https://github.com/bhavinpandya84/ecommerceproject/blob/master/ECommerce.Orders/Program.cs) (Application Startup), [`ECommerce.Orders/Controllers/OrderController.cs`](https://github.com/bhavinpandya84/ecommerceproject/blob/master/ECommerce.Orders/Controllers/OrderController.cs) (Order API)
