In this section, we are going to explain how easy and fast it is to install Visual Studio Code on Linux. One of the most popular Linux distributions, Ubuntu 16.04, will serve as an example.

If you do not have a physical or virtual installation of Linux Ubuntu available, you can easily install it in Azure to try out Visual Studio Code and understand the various ASP.NET Core 3 examples. By doing this, you can connect via the Microsoft Remote Desktop app.

In this case, select the Linux Ubuntu 18.04 LTS image from the Azure Marketplace and create a new Linux Ubuntu VM in Azure. Leave all of the default options and configure it to allow remote desktop connections (install a compatible desktop, install xrdp, open port 3389, and more):

Let's learn how to install Visual Studio Code on Linux Ubuntu:

1. First, download the Linux Ubuntu installation .deb package (64-bit) from https://go.microsoft.com/fwlink/?LinkID=760868

2. Open a new Terminal window in Ubuntu.
3. Install the downloaded package via sudo dpkg -i <file>.deb.
4. Then, enter sudo apt-get install -f.
5. Set Visual Studio Code as your default text file editor by typing in the xdg-mime default code.desktop text/plain command.

The installation will begin and automatically install the APT repository and signing key to enable automatic package updates, as well as Visual Studio Code:

You can also manually install the repository and signing key, update the package cache, and start the Visual Studio Code package installation, as follows:

1. Open a new Terminal window in Ubuntu:

curl https://packages.microsoft.com/keys/microsoft.asc | gpg --
 dearmor>microsoft.gpg

sudo mv microsoft.gpg /etc/apt/trusted.gpg.d/microsoft.gpg

sudo sh -c 'echo "deb [arch=amd64]
 https://packages.microsoft.com/repos/vscode stable main" > 
  /etc/apt/sources.list.d/vscode.list'

sudo apt-get update

sudo apt-get install code

2. Set Visual Studio Code as your default text file editor by typing in the xdg-mime default code.desktop text/plain command.

At this point, we have our environment ready and can create our first ASP.NET Core application in our new Linux environment.
