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.
