ASP.NET Core Minimal APIs: Building Lightweight REST APIs

Modern web development demands lightweight, fast, and maintainable services without the overhead of traditional controller-based architectures. ASP.NET Core Minimal APIs offer a streamlined approach to building high-performance HTTP services with minimal boilerplate code. In this comprehensive text-only guide, you will transition from understanding core web concepts to structuring and writing clean, production-ready APIs. You will gain the confidence to construct modern backends using the latest C# features and clean architecture principles. What you will learn: Understand the foundational concepts of RESTful services and how Minimal APIs differ from traditional controllers; Configure routing, map HTTP methods, and handle request payloads with modern C# syntax; Implement dependency injection to manage application services and database contexts cleanly; Apply validation, handle errors gracefully, and return appropriate HTTP status codes; Organize your codebase using modern route groups and clean architecture patterns for scalability; Secure your endpoints with modern authentication and authorization configurations. The course begins with essential web terminology and basic routing setup, before gradually guiding you through database integration, data validation, and structuring your application for production. You will learn through clear, step-by-step written explanations and practical code snippets. This course is designed for beginner developers, software engineers, or anyone familiar with basic C# who wants to learn modern API development without any prior ASP.NET Core experience.
