ASP.NET Core Web API

A simple Web API built with ASP.NET Core 8.
This project demonstrates how to create a RESTful API using controllers, routing, and dependency injection.
It’s based on the official Microsoft tutorial for learning the fundamentals of building APIs in .NET.

Notes

• Uses an in-memory database, so data is not persisted after restarting the app.
• Created for educational purposes — not intended for production use.
• You can easily replace the in-memory DB with a real database (e.g., SQLite, PostgreSQL, SQL Server).
• Great for beginners learning ASP.NET Core Web API and Entity Framework Core.
