Gabriel Baptista, Francesco Abbruzzese

Software architecture is the practice of implementing structures and systems that streamline the software development process and improve the quality of an app. This fully revised and expanded third edition, featuring the latest features of .NET 6 and C# 10, enables you to acquire the key skills, knowledge, and best practices required to become an effective software architect.Software Architecture with C# 10 and .NET 6, Third Edition features new chapters that describe the importance of the software architect, microservices with ASP.NET Core, and analyzing the architectural aspects of the front-end in the applications, including the new approach of .NET MAUI. It also includes a new chapter focused on providing a short introduction to artificial intelligence and machine learning using ML.NET, and updated chapters on Azure Kubernetes Service, EF Core, and Blazor.You will begin by understanding how to transform user requirements into architectural needs and exploring the differences between functional and non-functional requirements. Next, you will explore how to choose a cloud solution for your infrastructure, taking into account the factors that will help you manage a cloud-based app successfully. Finally, you will analyze and implement software design patterns that will allow you to solve common development problems.By the end of this book, you will be able to build and deliver highly scalable enterprise-ready apps that meet your business requirements.

XNA 4.0 Game Development by Example: Beginner's Guide - Visual Basic Edition. Create your own exciting games with Visual Basic and Microsoft XNA 4.0

Kurt Jaegers

XNA Game Studio enables hobbyists and independent game developers to easily create video games, and now gives that power to Visual Basic developers. XNA lets you bring your creations to life on Windows, the Xbox 360 and the Windows Phone platforms. The latest release of XNA has added support to Visual Basic and therefore, Visual Basic developers now have the power to give life to their creativity with XNA.This book covers both the concepts and the implementations necessary to get you started on bringing your own creations to life with XNA. It presents four different games, including a puzzler, space shooter, multi-axis shoot 'em up, and a jump-and-run platformer. Each game introduces new concepts and techniques to build a solid foundation for your own ideas and creativity.This book details the creation of four games, all in different styles, from start to finish using Visual Basic and the Microsoft XNA framework. Beginning with the basics of drawing images to the screen, the book then incrementally introduces sprite animation, particles, sound effects, tile-based maps, and path finding. It then explores combining XNA with Windows Forms to build an interactive map editor, and builds a platform-style game using the editor-generated maps. Finally, the book covers the considerations necessary for deploying your games to the Xbox 360 platform.By the end of the book, you will have a solid foundation of game development concepts and techniques as well as working sample games to extend and innovate upon. You will have the knowledge necessary to create games that you can complete without an army of fellow game developers at your back.
