ASP.NET Core Minimal APIs for Beginners and Professionals: Build ultra-fast, lightweight RESTful Microservices with .NET 10, C# 14, and essential mode
暫譯: ASP.NET Core 最小化 API 入門與進階：使用 .NET 10、C# 14 和基本模式構建超快速、輕量級的 RESTful 微服務

This book is a complete guide to building modern, reliable, and production-ready APIs with ASP.NET Core Minimal APIs. It takes you from first principles to advanced implementation patterns used in professional backend development. You learn how to design endpoints, structure data flow, apply validation, implement security, manage performance, and prepare applications for real-world deployment.

Each chapter explains concepts in direct, practical language. All examples use clear code samples and well-defined steps so you move from reading to building without friction. You see how to use dependency injection, token based identity, role based access, routing rules, filters, error handling pipelines, EF Core data access, and performance profiling. You also learn how to test your services with unit tests, integration tests, and contract testing practices.
The book prepares you for long-term maintenance by showing stable response contracts, versioning strategies, logging practices, metrics, and distributed tracing.

This is a complete guide for developers who want strong fundamentals and consistent delivery standards across development, testing, and deployment. The content fits beginners entering web API development and experienced developers adopting Minimal APIs for faster and cleaner service design.
