Mastering APIs with ASP.NET 9: Design, Build, and Optimize Scalable APIs in C# with .NET 9

APIs power the digital world, enabling seamless interactions between applications, cloud services, and enterprise systems. As modern applications demand scalability, efficiency, and security, mastering API development is no longer optional-it is essential.

This book is a comprehensive, hands-on guide to building high-performance APIs using ASP.NET 9, equipping developers with the knowledge and practical techniques required to design, implement, and optimize scalable, secure, and maintainable APIs. Whether you're developing RESTful APIs, GraphQL services, real-time communication layers, or microservices architectures, this book provides end-to-end coverage of API best practices.

• Master API design principles and RESTful best practices to ensure your APIs are intuitive, well-structured, and scalable.
• Implement secure authentication and authorization with OAuth 2.1, JWT, API Keys, and role-based access control to protect APIs from unauthorized access.
• Leverage cutting-edge performance optimization techniques including caching, asynchronous programming, and API rate limiting to build lightning-fast APIs.
• Explore modern API architectures like GraphQL, gRPC, and microservices to create flexible, efficient, and scalable backend solutions.
• Deploy serverless APIs using Azure Functions for cost-efficient, event-driven applications that scale dynamically.
• Integrate observability tools like OpenTelemetry, Application Insights, and Prometheus to monitor API performance and detect failures in real time.
• Connect APIs to databases with Entity Framework Core 9, implement the repository pattern, and execute high-performance SQL queries.
• Automate API testing with Postman, Swagger, and unit testing frameworks to ensure robustness and reliability.

This book is designed for backend developers, software architects, and API engineers who want to master API development with ASP.NET 9.
