## What it is
An ASP.NET Core backend implementation of the RealWorld (Medium.com clone) spec, demonstrating CRUD, JWT authentication, pagination, and vertical-slice architecture. It serves as a reference codebase showing how to build a fully fledged API with CQRS, EF Core, FluentValidation, and Swagger.

## Use cases
- learn how to build a real-world ASP.NET Core API
- reference implementation of vertical slice architecture in C#
- example of CQRS with Mediator in .NET
- JWT authentication example for ASP.NET Core
- compare backend implementations against the RealWorld API spec
- starting point for a Medium.com clone backend
- see Entity Framework Core with SQLite and SQL Server in practice

## When to choose
- you want a spec-compliant RealWorld backend in ASP.NET Core
- you are learning modern .NET API patterns like CQRS and vertical slices
- you need a reference for JWT auth, validation, and Swagger setup in ASP.NET Core
- you want to pair a RealWorld frontend with a .NET backend

## When to avoid
- you need a production-ready application rather than a reference/demo codebase
- your stack is not .NET/C#
- you need features beyond the RealWorld spec such as file uploads or real-time messaging
