Book Description:

C# and .NET continue to power modern cross-platform and enterprise development. With the release of C# 14 and .NET 10, developers gain access to a more capable, efficient, and future-ready platform for building websites, services, and applications across Windows, Linux, and macOS.

This fully updated tenth edition takes a practical, hands-on approach. You'll start with core C# and object-oriented programming concepts, then progress through building, testing, and debugging applications while working with .NET libraries, filesystems, serialization, and LINQ. The book covers key C# 14 enhancements-such as field modifiers, partial events, and instance constructors, explained through real-world examples.

You'll also build modern web solutions using ASP.NET Core 10, Blazor, and Minimal APIs, including support for native AOT compilation, making this book well suited for cloud-native, microservice, and container-based development.

By the end of the book, you'll be confident in building maintainable, high-performance websites and services aligned with modern .NET development practices.

What You Will Learn:

- Discover the new features in .NET 10, including the NumericOrdering option and OrderedDictionary enhancements

- Leverage the latest ASP.NET Core 10 features, such as OpenAPI 3.1 document generation, YAML format support, and populating XML doc comments

- Use native AOT publishing for faster startup and reduced memory footprint

- Build rich web user interface experiences with Blazor

- Integrate databases into your applications using EF Core 10 entity models

- Query and manipulate data using LINQ

- Develop powerful web services with Minimal APIs

Who this book is for:

This book is for beginner-to-intermediate C# and .NET developers who want to build modern, cross-platform websites and services. Prior experience with C# or .NET is helpful but not required; a basic understanding of programming concepts is sufficient.
