C# 11 and .NET 7 – Modern Cross-Platform Development Fundamentals - Seventh Edition

4.2 (5)
By: Mark J. Price

Overview of this book

Extensively revised to accommodate the latest features that come with C# 11 and .NET 7, this latest edition of our guide will get you coding in C# with confidence. You’ll learn object-oriented programming, writing, testing, and debugging functions, implementing interfaces, and inheriting classes. 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. Having mastered the basics, you’ll then start building websites, web services, and browser apps. By the end of this book, you’ll be able to create rich web experiences and have a solid grasp of object-oriented programming that you can build upon.

Building web services using Minimal APIs

For .NET 6, Microsoft put a lot of effort into adding new features to the C# 10 language and simplifying the ASP.NET Core libraries to enable the creation of web services using Minimal APIs. Minimal APIs are designed to enable the creation of HTTP APIs with minimum lines of code.

Minimal APIs are covered in more detail in my companion book, Apps and Services with .NET 7, in Chapter 9, Building and Securing Web Services with Minimal APIs.

You might remember the weather forecast service that is provided in the Web API project template. It shows the use of a controller class to return a five-day weather forecast using faked data. We will now recreate that weather service using Minimal APIs.

It will listen on port 5003 and only GET requests are allowed:
