ASP.NET Core Fundamentals: Building Modern Web Applications With .NET 10

ASP.NET Core Fundamentals
Building Modern Web Applications with .NET 10 Build fast. Build secure. Build production-ready.

ASP.NET Core Fundamentals is a practical, modern guide to building real-world web applications using .NET 10 and ASP.NET Core . Whether you are developing APIs, server-rendered web apps, or high-performance services, this book gives you the architectural clarity and hands-on knowledge required to build with confidence.

This is not a shallow overview. It is a structured, end-to-end journey through the modern ASP.NET Core ecosystem. From foundational concepts to deployment and performance tuning.

If you want to understand not just how ASP.NET Core works, but why it is designed the way it is, this book is for you.

What You’ll Learn

Part I: Foundations • Understand ASP.NET Core architecture and the minimal hosting model in .NET 10
• Master project structure, configuration, dependency injection, and secrets management
• Build and customize middleware and control the HTTP request pipeline
• Design maintainable routing and endpoint strategies

Part II: Building Web Applications • Compare Controllers and Minimal APIs and choose the right approach
• Build server-rendered applications with Razor Pages
• Implement forms, model binding, and validation correctly
• Secure applications with authentication, Identity, and policy-based authorization

Part III: Data and Architecture • Integrate Entity Framework Core with performance and concurrency in mind
• Apply clean architecture and service layer patterns
• Implement caching, rate limiting, and resilience strategies

Part IV: APIs, Testing, and Observability • Design clean, consistent RESTful APIs
• Generate and customize OpenAPI and Swagger documentation
• Implement API versioning and understand Native AOT considerations
• Write unit and integration tests using xUnit and WebApplicationFactory
• Add logging, tracing, metrics, and health checks for production visibility

Part V: Production and Deployment • Profile and optimize performance
• Tune Kestrel and improve memory usage
• Deploy with Docker and CI/CD pipelines
• Understand when and how to use Native AOT in ASP.NET Core

Who This Book Is For • C# developers moving into web development
• .NET developers upgrading to .NET 10
• Backend engineers building APIs and distributed systems
• Developers who want to move beyond tutorials and build production-grade systems

Why This Book Is Different This book emphasizes:

Architectural clarity Practical examples Real-world patterns Production-ready thinking You will not just build sample apps, you will learn how to structure applications that scale, remain maintainable, and perform under load.

ASP.NET Core is one of the most powerful and flexible web frameworks available today. With .NET 10, it is faster and more capable than ever.

Master it properly.
Build with confidence.
