Your hands-on guide to Visual C# fundamentals with Visual Studio 2022

Expand your expertise—and teach yourself the fundamentals of programming the latest version of Visual C# with Visual Studio 2022. This book provides software developers all the guidance, exercises, and code needed to start building responsive, scalable, cloud-connected applications that can run almost anywhere.

Discover how to:

• Quickly start creating Visual C# code and projects with Visual Studio
• Work with variables, operators, expressions, methods, and program flow
• Build more robust apps with error, exception, and resource management
• Spot problems fast with the integrated Visual Studio 2022 debugger
• Master new default interface methods, static local functions, async disposable types, and other enhancements
• Make the most of the C# object model, and create functional data structures
• Leverage advanced properties, indexers, generics, and collection classes
• Create Windows 11 apps that share data, collaborate, and use cloud services
• Use lightweight records to build immutable reference types more easily
• Perform complex queries over object collections with LINQ
• Improve application throughput and response time with asynchronous methods
• Use delegates and decoupling to construct highly extensible systems
• Customize C# operator behavior over your own classes and structures
• Implement the powerful Model-View-ViewModel (MVVM) pattern
• Build UWP applications that retrieve complex data and present it intuitively
