Next, you'll take on .NET APIs for performing tasks like managing and querying data, working with the filesystem, and serialization. As you progress, you'll also explore examples of cross-platform projects you can build and deploy, such as websites and services using ASP.NET Core.Instead of distracting you with unnecessary graphical user interface code, the first eleven chapters will teach you about C# language constructs and many of the .NET libraries through simple console applications. In later chapters, having mastered the basics, you'll then build websites, web services, and browser apps using ASP.NET Core, the Model-View-Controller (MVC) pattern, and Blazor.C# 11 and .NET 7 - Modern Cross-Platform Development Fundamentals will give you a solid foundation to start building apps and services with confidence. By the end of this book, you'll be able to create rich web experiences and have a solid grasp on object-oriented programming that you can build upon.What You Will Learn:Build rich web experiences using Blazor, Razor Pages, the Model-View-Controller (MVC) pattern, and other features of ASP.NET CoreBuild your own types with object-oriented programmingWrite, test, and debug functionsQuery and manipulate data using LINQIntegrate and update databases in your apps using Entity Framework Core modelsBuild and consume powerful services using the latest technologies, including Web API and Minimal APIWho this book is for:This book is primarily for beginners, but intermediate-level C# and .NET programmers who have worked with C# in the past and want to catch up with the changes made in the past few years will also find plenty of useful information in it. Prior exposure to C# or .NET is not a prerequisite, but you should have a general understanding of programming before you jump in.If you already have some C# and .NET skills and want to focus on developing apps, we recommend that you pick up Mark's other .NET book, Apps and Services with .NET 7, instead.

Learn how to write software that excites your customers and avoids breaking your work when making changesKey Features:Learn how a simple shift in focus will let you use tests to meet customer needsDevelop a testing library and a logging library that you can use in your own projectsDrive better code designs with effective tests that help new team members contribute fasterBook Description:Modern, standard C++ is all that is needed to create a small and practical testing framework that will improve the design of any project. This allows you to think about how the code will be used, which is the first step in designing intuitive interfaces.
