Create API Controller

Create a controller for a given entity in an ASP.NET Core Web API project.

Pre-requisites

• Use Controller-based APIs
• Use System.Text.Json for all JSON data
• The project uses Entity Framework Core 9 — do not install additional packages, the project is already set up.

Steps

1. Create an empty controller with the naming rule: {EntityName}Controller

2. Set up DI and inject Entity Framework context and ILogger<T>.

3. Do not use Entity Class for model binding. Create DTO classes for each CRUD operation instead.

4. Add CRUD REST API methods with required OpenAPI-related annotations.
