Look inside

The development team at Boutique, a software company, is working on a project for automating the inspection process of a client that builds industrial robots. An ASP.NET Core HTTP API has already been set up, and the team has started implementing the domain model entities and persisting them to a SQL database. As part of the team, your task is to implement CRUD (create, read, update, and delete) endpoints for all the entities according to the OpenAPI specification. To achieve persistence, you’ll configure Entity Framework Core and register it in the dependency injection container. You’ll implement a custom JSON converter to support polymorph endpoints in order to handle different types of robots. To verify that your implementation is correct, you’ll write and perform integration tests.

This project is designed for learning purposes and is not a complete, production-ready application or solution.
