C# 14 and .NET 10 – Modern Cross-Platform Development Fundamentals

Summary

In this chapter, we did the following:

Set up your development environment.
Used Visual Studio and VS Code with the .NET SDK CLI to create a couple of simple console apps, grouped in a solution.
Learned how to download the solution code for this book from its GitHub repository.
Learned how to find help. This could be in the traditional way, by using help command switches, documentation, and articles, or the modern way, by having a conversation with a coding expert AI or using an AI-based tool to perform “grunt work.”

In the next chapter, you will learn how to “speak” C#.

Exploring more about console apps

Console apps are text-based and are run at the command prompt. They typically perform simple tasks that need to be scripted, such as compiling a file or encrypting a section of a configuration file. Equally, they can also have arguments passed to them to control their behavior.

An example of this would be to create a new console app using the F# language with a specified name instead of using the name of the current folder, as shown in the following command:

dotnet new console -lang "F#" --name "ExploringConsole"

Displaying output to the user

The two most common tasks that a console app performs are writing and reading data. We have already used the WriteLine method to output, but if we didn’t want a carriage return at the end of a line, for example, if we later wanted to continue to write more text at the end of that line, we could have used the Write method.

If you want to write three letters to the...

Description

C# and .NET continue to power modern cross-platform and enterprise development. With the release of C# 14 and .NET 10, developers gain access to a more capable, efficient, and future-ready platform for building websites, services, and applications across Windows, Linux, and macOS. This fully updated tenth edition takes a practical, hands-on approach.

The book covers key C# 14 enhancements—such as field modifiers, partial events, and instance constructors, explained through real-world examples. You’ll also build modern web solutions using ASP.NET Core 10, Blazor, and Minimal APIs, including support for native AOT compilation, making this book well suited for cloud-native, microservice, and container-based development. By the end of the book, you’ll be confident in building maintainable, high-performance websites and services aligned with modern .NET development practices.

What is custom duty/charge?

Customs duty are charges levied on goods when they cross international borders. It is a tax that is imposed on imported goods. These duties are charged by special authorities and bodies created by local governments and are meant to protect local industries, economies, and businesses.

Do I have to pay customs charges for the print book order?

The orders shipped to the countries that are listed under EU27 will not bear custom charges. They are paid by Packt as part of the order.

List of EU27 countries: www.gov.uk/eu-eea:

A custom duty or localized taxes may be applicable on the shipment and would be charged by the recipient country outside of the EU27 which should be paid by the customer and these duties are not included in the shipping charges been charged on the order.

How do I know my custom duty charges?

The amount of duty payable varies greatly depending on the imported goods, the country of origin and several other factors like the total invoice amount or dimensions like weight, and other such criteria applicable in your country.

For example:

If you live in Mexico, and the declared value of your ordered items is over $ 50, for you to receive a package, you will have to pay additional import tax of 19% which will be $ 9.50 to the courier service.
Whereas if you live in Turkey, and the declared value of your ordered items is over € 22, for you to receive a package, you will have to pay additional import tax of 18% which will be € 3.96 to the courier service.

BillW Jan 19, 2026

Once again this book is the perfect way to learn how to code in C#. With it's latest iteration of C#14 and .NET 10, learning what's new and how to code to it from someone who has been teaching .NET for years is the way to go. I've owned each edition of this book since .NET 3 and it just keeps getting better and better.
