Step-by-Step Guide to Installing and Running C# in Visual Studio Code

C# (pronounced C Sharp) is a versatile and robust programming language used extensively in developing various applications, from web to desktop. If you’re an aspiring programmer or developer looking to work with C#, Visual Studio Code (VS Code) is a fantastic tool to start with. It is lightweight, powerful, and equipped with numerous extensions that enhance your coding experience. This article will guide you through the process of installing and running C# in Visual Studio Code step-by-step.

Why Use Visual Studio Code for C#?

Visual Studio Code stands out as one of the most popular code editors due to its flexibility and functionality. For C# developers, it offers substantial support through extensions that help create, debug, and run C# applications seamlessly. By choosing VS Code, you gain access to:

  • A lightweight interface that enhances productivity.
  • A vast library of extensions catered to C# programming.
  • Built-in terminal to run commands directly from the code editor.

Prerequisites

Before you get started, ensure you have:

  • A computer running either Windows or macOS.
  • Internet access to download the necessary software.

Step 1: Download and Install the .NET SDK

To start programming in C#, you need the .NET SDK. Here’s how to download and install it:

  1. Visit the .NET downloads page: Go to https://dotnet.microsoft.com/download.
  2. Select the appropriate version: Choose the version based on your operating system. If you’re on macOS, opt for the version compatible with Apple Silicon.
  3. Install the SDK:
  • On Windows: Download the installer and follow the instructions.
  • On macOS: Download the .dmg file and drag it to Applications.

Step 2: Download and Install Visual Studio Code

Next, you need to download and set up Visual Studio Code:

  1. Visit the Visual Studio Code website: Go to https://code.visualstudio.com/.
  2. Download VS Code: Click on the download button suitable for your system (Windows or macOS).
  3. Install VS Code:
  • On Windows: Run the downloaded file and follow the setup prompts.
  • On macOS: Open the .dmg file and drag the VS Code icon to Applications.

Step 3: Install Necessary Extensions in VS Code

Once you have both the .NET SDK and Visual Studio Code installed, you need to add essential extensions for C# development:

  1. Open Visual Studio Code.
  2. Access the Extensions View: Click on the Extensions icon in the Activity Bar on the side or simply press Ctrl+Shift+X (or Cmd+Shift+X on macOS).
  3. Install required extensions: Look for and install the following:
  • C# for Visual Studio Code (powered by OmniSharp) – This is crucial.
  • C# Dev Kit – Enhances code-writing functionality.
  • IntelliCode for C# Dev Kit – Adds AI-assisted capabilities for coding.
  • Optional but recommended: Code Runner – This allows you to execute code quickly from the editor.

Step 4: Create Your First C# Project

After setting up your tools, it’s time to create a C# project:

  1. Open a new folder in VS Code: Click on File > Open Folder, then create a new folder named something like CSharpProjects and select it.
  2. Open the Command Palette: You can access it via View > Command Palette or by pressing Ctrl+Shift+P (or Cmd+Shift+P on macOS).
  3. Create a new project: Type .NET: New Project and hit Enter.
  • Choose Console App when prompted.
  • Provide a project name (e.g., “HelloWorld”).
  • Select the default directory if prompted and confirm.

Step 5: Running Your C# Application

Once your project is created, you’re ready to run it:

  1. Open your terminal in VS Code by clicking on Terminal > New Terminal.
  2. Use the command to run your application: Type the following command:
   dotnet run
  1. View the output: You should see output from your C# application in the terminal. If you created a console app titled “HelloWorld”, it might simply print “Hello, World!”.

Common Issues and Troubleshooting

  • Project not found issue: If you encounter an error saying it can’t find the project, ensure you are in the correct directory. Use the cd command in the terminal to navigate to your project folder.
  • Missing extensions: Ensure you have installed the C# extensions properly, as they are vital for running C# code in VS Code.

Conclusion

By following this guide, you should have a functional C# development environment set up in Visual Studio Code. This setup enables you to create, run, and manage your C# projects efficiently. Whether you are learning C# for the first time or looking to enhance your existing skills, VS Code provides the tools you need to succeed.
