.NET SDK

The .NET SDK is a free, open-source, cross-platform development environment that provides tools and libraries for building applications. You can use it to create web apps, mobile apps, desktop apps, cloud services, and more.

.NET 10 is the latest Long Term Support (LTS) release. .NET 9 (Standard Term Support) and .NET 8 (LTS) are also available. This guide defaults to .NET 10, with instructions for selecting an alternative version.

The .NET SDK is available for Linux distributions on Arm-based systems.

What should I do before installing the .NET SDK on Arm Linux?

Confirm you are using an Arm machine by running:

    

        
        
uname -m

    

The output should be:

    

        
        aarch64

        
    

If you see a different result, you are not using an Arm computer running 64-bit Linux.

How do I install the .NET SDK on my Arm Linux system?

There are two ways to install the .NET SDK on your computer:

• Using the Linux package manager.
• Using the install script.

Select the one that works best for you.

How can I install .NET SDK using the Linux package manager?

Use apt to install the .NET 10 SDK on Ubuntu and Debian:

    

        
        
sudo apt-get update && sudo apt-get install -y dotnet-sdk-10.0

    

Use dnf to install the .NET 10 SDK on Fedora:

    

        
        
sudo dnf install dotnet-sdk-10.0

    

To install a different version, replace 10.0 with the version you need. For example, use dotnet-sdk-9.0 for .NET 9 or dotnet-sdk-8.0 for .NET 8.

If the .NET SDK is not found in your package manager, you can install it using a script.

How can I install .NET SDK using a script?

To install the .NET SDK using a script, follow the instructions below:

1. Download the install script:

    

        
        
wget https://dot.net/v1/dotnet-install.sh

    

2. Run the script to install the .NET SDK under the $HOME/.dotnet folder.

You have several options for specifying the version.

To install the latest LTS version (.NET 10), run:

    

        
        
bash ./dotnet-install.sh

    

To install the latest available version (including STS releases), run:

    

        
        
bash ./dotnet-install.sh --version latest

    

To install a specific version channel, use the --channel flag. For example, to install .NET 10:

    

        
        
bash ./dotnet-install.sh --channel 10.0

    

You can also use --channel 9.0 for .NET 9 or --channel 8.0 for .NET 8.

3. Add the .dotnet folder to the PATH environment variable:

    

        
        
export PATH="$HOME/.dotnet/:$PATH"

    

You can also add the search path to your $HOME/.bashrc so it is set for all new shells.

How do I verify the .NET SDK installation?

To check that the installation was successful, run:

    

        
        
dotnet --list-sdks

    

The output is similar to:

    

        
        10.0.103 [/usr/lib/dotnet/sdk]

        
    

For more detailed information about your installation, run:

    

        
        
dotnet --info

    

The output is similar to:

The exact version numbers depend on when you install and which updates are available.

How can I run a simple example to confirm the .NET SDK is working?

Create a new console application to verify that the .NET SDK works correctly:

    

        
        
dotnet new console -o myapp

    

Change to the new directory and run the application:

    

        
        
cd myapp
dotnet run

    

The expected output is:

    

        
        Hello, World!

        
    

You are ready to use the .NET SDK on Arm Linux.
