Who this book is for

This book is for .NET developers interested in exploring more specialized libraries and implementation fundamentals behind building services and apps. You’ll need to know your way around .NET and C# quite well before you can dive in, so if you want to work your way up to this book, you can pick up Mark’s other .NET book, C# 12 and .NET 8 – Modern Cross-Platform Development Fundamentals, first.

This latest edition of the bestselling Packt series will give you a solid foundation to start building projects using modern C# and .NET with confidence.

You'll learn about object-oriented programming; writing, testing, and debugging functions; and implementing interfaces. You'll take on .NET APIs for managing and querying data, working with the fi lesystem, and serialization. As you progress, you'll explore examples of cross-platform projects you can build and deploy, such as websites and services using ASP.NET Core.

This latest edition integrates .NET 8 enhancements into its examples: type aliasing and primary constructors for concise and expressive code. You'll handle errors robustly through the new built-in guard clauses and explore a simplified implementation of caching in ASP.NET Core 8.

If that's not enough, you'll also see how native ahead-of-time (AOT) compiler publish lets web services reduce memory use and run faster. You'll work with the seamless new HTTP editor in Visual Studio 2022 to enhance the testing and debugging process. You'll even get introduced to Blazor Full Stack with its new unified hosting model for unparalleled web development flexibility.

What you will learn

• Discover C# 12's new features, including aliasing any type and primary constructors
• Try out the native AOT publish capability for ASP.NET Core 8 Minimal APIs web services
• Build rich web experiences using Blazor Full Stack, Razor Pages, and other ASP.NET Core features
• Integrate and update databases in your apps using Entity Framework Core models
• Query and manipulate data using LINQ
• Build and consume powerful services using Web API and Minimal API

Who this book is for

This book is for beginners as well as intermediate-level C# and .NET programmers who have worked with C# in the past and want to catch up with the changes made in the last few years. Prior exposure to C# or .NET is not a prerequisite. A general understanding of programming will help you to work through the book more comfortably, though the content is suitable for those completely new to programming. If you already have some C# and .NET skills and want to focus on developing practical apps, you can pick up Mark’s other .NET book, Apps and Services with .NET 8, instead.

Understand what to do at any point in developing a clean .NET architecture

Master advanced .NET techniques with a focus on actual value delivered by working within a modular, clean architecture. Microsoft Data Platform MVP Dino Esposito explains key clean architecture concepts with a mix of pragmatism and design discipline and helps you solidify your knowledge through a real-world project. Starting with an explanation of the quest for modular software architecture continuing through the methodology of domain-driven design (DDD), Esposito emphasizes the role that modularization plays in managing complexity in software development. Breaking down the layers of an architecture that is modular and maintainable, he presents a sample project that is not simply another to-do list, but an actual tool for the reader. Ultimately, an exploration of common dilemmas for both developers and operations brings together historical developments with real solutions for today.

Microsoft Data Platform MVP Dino Esposito helps you:

• Understand the relevance of modular software architecture in the history of software
• Review domain-driven design concepts both, strategic and practical
• Apply modular analysis techniques to your development
• Make the most of layered architecture
