Workflow fit

Identify the real job behind the article: coding, research, document review, support, analytics, content, or internal automation.

Model or tool decision

Decide whether the next step is a software shortlist, an AI tool comparison, an API platform choice, or a model benchmark.

Budget and usage signal

Estimate seats, API calls, prompt volume, retries, review time, and fallback work before assuming the workflow is cheap.

Security and privacy review

Check whether source code, customer data, private documents, prompts, logs, or embeddings will enter the AI workflow.

In the previous article, we gained a foundational understanding of the ASP.NET Core architecture. Next, we’ll dive into setting up your development environment. Installing the .NET SDK is the very first step in beginning ASP.NET Core development. This article provides detailed, step-by-step guidance for installing the .NET SDK across Windows, macOS, and Linux—so you can confidently launch your development journey.

What Is the .NET SDK?

The .NET SDK (Software Development Kit) is the essential toolkit required to build .NET applications. It includes tools needed to compile code, run applications, and perform other common development tasks. Once installed, the .NET SDK enables you to use the dotnet CLI (Command-Line Interface) to create, build, and run ASP.NET Core applications.

Installing the .NET SDK

Below are the installation instructions for Windows, macOS, and Linux.

Installation Steps on Windows

Download the .NET SDK:
Visit the .NET download page, select an appropriate version—preferably the latest stable release. You’ll see two primary options: Windows Installer and ZIP. We recommend using the Windows Installer.
Run the Installer:
After downloading, double-click the .exe file to launch the setup wizard, then follow the on-screen prompts to complete the installation.
Verify the Installation:
Open Command Prompt (CMD) and run the following command:
```
dotnet --version
```
If successful, this will display the version number of the installed .NET SDK.

Installation Steps on macOS

Install Homebrew (if not already installed):
Homebrew is macOS’s popular package manager, simplifying software installation. In Terminal, run:
```
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
```
Install the .NET SDK:
Use Homebrew to install the SDK by running the following command in Terminal:
```
brew install --cask dotnet-sdk
```
Configure the PATH Environment Variable:
Run this command in Terminal to add the .NET SDK directory to your PATH:
```
export PATH="$PATH:/usr/local/share/dotnet"
```
To make this change persistent across terminal sessions, add the above line to your ~/.bash_profile or ~/.zshrc file.
Verify the Installation:
In Terminal, execute:
```
dotnet --version
```
You should see the installed version number displayed.

Installation Steps on Linux

Installation steps vary slightly depending on your Linux distribution. Below are instructions specifically for Ubuntu.

Add Microsoft’s Package Signing Key:
Open Terminal and run:

wget https://packages.microsoft.com/config/ubuntu/$(lsb_release -rs)/packages-microsoft-prod.deb
sudo dpkg -i packages-microsoft-prod.deb

Install Required Dependencies:

sudo apt-get update
sudo apt-get install -y apt-transport-https
sudo apt-get update

Install the .NET SDK:
Install the latest stable version of the .NET SDK with:
```
sudo apt-get install -y dotnet-sdk-7.0
```
Verify the Installation:
In Terminal, run:
```
dotnet --version
```
Confirm that the correct version number appears.

Summary

In this article, we walked through installing the .NET SDK on the three major operating systems—Windows, macOS, and Linux—laying the essential groundwork for your ASP.NET Core development. Regardless of your platform, following these steps will get you up and running quickly. Next, we’ll explore how to configure an optimal development environment to maximize productivity.

Stay enthusiastic and patient as you learn ASP.NET Core! In the next article, we’ll delve deeper into configuring your development environment—so let’s keep this learning journey going!
