Deploying ASP.NET Core

Most ASP.NET Core developers know how to build applications. Far fewer know how to ship them.

You can write clean controllers, structure your services, and connect to databases-but when it's time to deploy, everything changes. Environments behave differently. Configuration breaks. Performance shifts. Security risks appear. And suddenly, a working application is no longer enough.

Deploying ASP.NET Core is the practical, production-focused guide that bridges the gap between development and real-world delivery. This book shows you how to take an ASP.NET Core application from your local machine to a reliable, scalable, and production-ready system.

Inside, you will learn how to:

• Publish and prepare ASP.NET Core applications for deployment
• Host applications on Windows (IIS) and Linux environments
• Configure reverse proxies like Nginx for real-world traffic handling
• Diagnose and fix deployment failures with structured troubleshooting approaches
• Package applications using Docker and run them consistently across environments
• Build automated CI/CD pipelines using GitHub Actions
• Manage configuration safely across development, staging, and production
• Secure sensitive data using modern secrets management practices
• Monitor application health, logs, and performance in production
• Scale applications effectively using proven architectural patterns

This is not a theory-heavy book. Every concept is grounded in real deployment scenarios, using a consistent project to demonstrate how systems behave under production conditions. You will not just follow steps-you will understand why those steps matter, how systems fail, and how to design deployments that hold up under pressure.

By the end of this book, you will be able to confidently design, deploy, and maintain ASP.NET Core applications in real environments. You will think beyond "it works" and start building systems that are stable, observable, and ready for scale.

If you are ready to move from development to delivery-and from applications to production systems-this book will guide you every step of the way.
