After installation, open a terminal or command prompt and run:

dotnet --version

✅ If installed correctly, you will see the version number (e.g., 8.0.2).

  3. 3️⃣ Run the installer and select “.NET Desktop Development” and “ASP.NET and Web Development” workloads.
  4. 4️⃣ Click "Install" and wait for the process to complete.

🔹 Option 2: Visual Studio Code (VS Code)

Why Use VS Code?

  • ✅ Lightweight, fast, and extensible.
  • ✅ Ideal for small projects, microservices, and cross-platform development.

🛠 Step 1: Download & Install VS Code

  1. 1️⃣ Go to the official website: https://code.visualstudio.com/download
  2. 2️⃣ Download and install for Windows, macOS, or Linux.

🛠 Step 2: Install C# Extension

  1. 1️⃣ Open VS Code.
  2. 2️⃣ Go to Extensions (Ctrl+Shift+X).
  3. 3️⃣ Search for "C# for Visual Studio Code" (by Microsoft).
  4. 4️⃣ Click Install.

🔹 3️⃣ Create and Run Your First .NET App

🛠 Step 1: Create a New .NET Console App

Open Command Prompt/Terminal and run:

dotnet new console -o MyFirstApp
cd MyFirstApp

🛠 Step 2: Open Project in VS Code or Visual Studio

🔹 For VS Code:

code .

🔹 For Visual Studio:

  • Open Visual Studio → Click "Open a project or solution" → Select the MyFirstApp folder.

🛠 Step 3: Run the Application
