Azure Database for PostgreSQL with C#: A Practical Guide to Cloud-Based Database Development

In a world where cloud computing and data-driven applications dominate, mastering cloud-based database solutions is essential for every modern developer and IT professional. Azure Database for PostgreSQL with C# offers a comprehensive, hands-on guide to integrating Microsoft's powerful Azure cloud platform with the robust PostgreSQL database engine—using the C# programming language. Whether you are a developer, database administrator, or technical architect, this book equips you with the knowledge and tools you need to build scalable, secure, and efficient applications in the cloud.

This book begins by introducing Azure Database for PostgreSQL, comparing the available deployment options, and showing how to set up your PostgreSQL server in Azure. It then guides you through the essential SQL features of PostgreSQL and how to manage them in a cloud-based environment. You will learn how to establish secure connections using C#, configure your development environment with Npgsql, and use Entity Framework Core to manage data more effectively.

Each chapter provides practical code examples, deployment strategies, and real-world insights. From basic CRUD operations to advanced performance tuning and security configurations, you will gain a strong understanding of how to work with PostgreSQL in Azure using .NET technologies. The book also includes guidance on authentication, monitoring, troubleshooting, and deploying production-grade applications using CI/CD pipelines.

With a focus on best practices and real-world application, this guide helps you avoid common pitfalls while ensuring your cloud-based architecture is robust, secure, and maintainable. Whether you are building a new SaaS product, migrating from on-premise infrastructure, or looking to deepen your cloud database expertise, this book will serve as a vital resource.
