Environment Setup

Setting up your environment for C# development involves installing the necessary tools and configuring your development environment. This guide covers the steps required to set up a development environment for C# 12, including installing .NET SDK, choosing an Integrated Development Environment (IDE), and writing your first C# program.

1. Install .NET SDK

The .NET SDK includes the tools you need to develop and run .NET applications. To install the .NET SDK, follow these steps:

2. Choose an Integrated Development Environment (IDE)

An Integrated Development Environment (IDE) provides a comprehensive environment for writing, debugging, and testing your code. Here are some popular IDEs for C# development:

3. Verify Installation

After installing the .NET SDK and choosing an IDE, verify your setup by running the following command in your terminal or command prompt:

Command: dotnet --version

This command should output the version of the .NET SDK installed, confirming that the installation was successful.

4. Write Your First C# Program

Let's write a simple "Hello, World!" program to verify that everything is set up correctly.

4.1 Create a New Project

Open your terminal or command prompt, navigate to the directory where you want to create your project, and run the following command:

Command: dotnet new console -n HelloWorld

This command creates a new console application in a folder named "HelloWorld".

4.2 Write the Code

Open the "Program.cs" file in your IDE and replace its content with the following code:

Example: 
        
            using System;

namespace HelloWorldApp
{
    class Program
    {
        static void Main(string[] args)
        {
            Console.WriteLine("Hello, World!");
        }
    }
}
4.3 Run the Program

Navigate to the project directory and run the following command to execute your program:

Command: dotnet run

You should see the output "Hello, World!" in the terminal, confirming that your environment is set up correctly.
