Install .NET SDK and .NET Runtime on Ubuntu 24.04 LTS

In this article we are going to cover Install .NET SDK and .NET Runtime on Ubuntu 24.04 LTS.

In 2016, Microsoft released .NET Core (what is now simply called .NET) as a completely new implementation of the platform. .NET applications can be distributed as either self-contained or framework-dependent executables. Self-contained applications already include the necessary .NET runtime files and libraries needed to run the application.

Prerequisites:

• Ubuntu 24.04 LTS with minimum 2GB RAM and 1 CPU.
• SSH access with sudo privileges

Step#1:Download and Install .NET SDK and .NET Runtime on Ubuntu

Let’s start the hands-on lab to install .NET SDk and .NET Runtime on ubuntu 24.04 LTS

Update the system packages on Ubuntu 24.04 LTS

sudo apt update

Install .NET SDK (Software Development Kit) to build and run.NET applications.

sudo apt install -y dotnet-sdk-8.0

Output:

Selecting previously unselected package dotnet-host-8.0.

Additionally, you may also need to install the .NET Runtime if you’re running applications that were built with .NET but don’t include the runtime.

sudo apt install -y aspnetcore-runtime-8.0

Install the ASP.NET Core Runtime, which is the most compatible runtime for .NET 8.0. Alternatively, you can install the .NET Runtime without the ASP.NET Core components by using the following command.

sudo apt install -y dotnet-runtime-8.0

Verify the installation by running the below command

dotnet --version

Output:

ubuntu@ip-172-31-0-129:~$ dotnet --version
8.0.107

You can try creating a new .NET project to ensure that the installation was successful.

dotnet new console -o my-app
cd my-app
dotnet run

Output:

ubuntu@ip-172-31-0-129:~$ dotnet new console -o my-app
