C# is undeniably one of the most versatile programming languages available to engineers today. With this comprehensive guide, you'll learn just how powerful the combination of C# and .NET can be. Author Ian Griffiths guides you through C# 12.0 and .NET 8 fundamentals and techniques for building cloud, web, and desktop applications. Designed for experienced programmers, this book provides many code examples to help you work with the nuts and bolts of C#, such as generics, LINQ, and asynchronous programming features. You'll get up to speed on .NET 8 and the latest C# 11.0 and 12.0 additions, including generic math, new polymorphism options, enhanced pattern matching, and new features designed to improve productivity. C# 11.0 and 12.0 have gained performance-oriented features including generic math, and improved control over memory handling for performance-sensitive low-level code. Every new .NET release has improved execution speed, but there have also been significant reductions in startup times, memory footprint, and binary size. This, along with improved support for containerization, enhances .NET’s fit for modern cloud development. There have also been significant improvements for cross-platform client-side development, thanks to Blazor and .NET MAUI (Multi-platform App UI). .NET has supported ARM and WebAssembly (WASM) for many years, but continuous recent improvements for those targets are important for cloud, mobile, and web development.
