Modern APIs with .NET 9 and C#

Are you still coding C# like it's 2015?

The .NET ecosystem has changed radically. Forget heavy configuration files, bloated Controllers, and past sluggishness. .NET 9 is here to compete head-to-head with Node.js and Go, offering one of the fastest and most efficient backend platforms in the global market.

In this practical, hands-on guide, you will leave academic theory behind to build a professional API from scratch to deploy. Written for the modern developer, this book teaches you how to cut through code bureaucracy and focus on what matters: performance and scalability.

What you will master:

• Minimal APIs: Create powerful endpoints with just a few lines of code.

• Extreme Performance: Native AOT techniques, ValueTask, and optimized memory allocation.

• Modern C#: Use Records, Pattern Matching, and Primary Constructors to write clean, safe code.

• Efficient Data: Entity Framework Core 9 with Bulk Updates and optimized queries.

• Bulletproof Security: Manual implementation of JWT, Claims, and Policies.

• DevOps Ready: Dockerization with Chiseled images and Cloud preparation.

Whether you are a .NET developer looking to upgrade your skills or a dev coming from JavaScript/Python wanting to understand the power of C#, this book is your field manual for the new era of high performance.
