C# 13 and .NET 9 – Modern Cross-Platform Development Fundamentals

Practicing and exploring

Let's now test your knowledge and understanding by trying to answer some questions, getting some hands-on practice, and going into the topics covered throughout this chapter in greater detail.

Exercise 1.1 – Online material

Online material can be extra content written by me for this book, or it can be references to content created by Microsoft or third parties.

Current versions of .NET

You can check what the latest version of .NET is for various platforms and what is officially supported at the following link: https://versionsof.net.

If you need to know more about support for the legacy .NET Framework, you can read about it at the following link: https://learn.microsoft.com/en-us/lifecycle/products/microsoft-net-framework.

Upgrade to a new .NET version

.NET releases new versions annually. Some developers begin upgrading as soon as a new version drops, while others prefer to wait until their current version reaches end-of-support. Upgrading involves...

We have already created and used basic console apps, but we’re now at a stage where we should delve into them more deeply.

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...

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.
