Downloading solution code from a GitHub repository

Git is a commonly used source code management system. GitHub is a company, website, and desktop application that makes it easier to manage Git. Microsoft recently purchased GitHub, so it will continue to get closer integration with Microsoft tools.

I used GitHub to store solutions to all the practical exercises that are featured at the end of each chapter. You will find the repository for this chapter at the following link:

If you like to use a GUI, you can download GitHub Desktop from the following link:

Cloning the book solution code repository

Let's clone the book solution code repository.

  1. Create a folder named Repos in your user or Documents folder, or wherever you want to store your Git repositories.
  2. In Visual Studio Code, open the Repos folder.
  3. Navigate to View | Terminal, and enter the following command:
    git clone
  1. Cloning all of the solutions for all of the chapters will take a minute or so, as shown in the following screenshot:
