Differences Between Console and Web Applications

As a beginner, you’ll often start with console apps. But C# is also used for web applications. What’s the difference?

🖥️ Console Applications

• Run in the terminal/command prompt.
• Input and output via text.
• Great for learning, automation, or simple utilities.
• Example:

  1
  2
  3
    Console.WriteLine("What is your name?");
    string? name = Console.ReadLine();
    Console.WriteLine($"Hello, {name}!");
  

🌐 Web Applications

• Run on a web server; users interact via browser.
• Built with ASP.NET Core (C#’s powerful web framework).
• Used for websites, APIs, dashboards, and more.
• Example (simplified):

  1
  2
    // In ASP.NET Core
    app.MapGet("/", () => "Hello, Web World!");
  

🎯 When to Use Each

Beyond Console and Web: Other .NET Application Types

While console and web applications are two of the most common project types in .NET, the platform supports a wide range of other possibilities. With .NET, you can also build:

• Mobile apps for iOS and Android using .NET MAUI or Xamarin.
• Desktop apps for Windows (WinForms, WPF) and macOS.
• Games for Windows, Xbox, and other platforms using Unity (which is powered by C#).
• Background services like Windows Services or daemons for Linux and macOS.
• Installers and deployment tools.
• Command-line utilities and automation scripts.
• Cloud/serverless functions for platforms like Azure Functions and AWS Lambda.

This flexibility makes .NET a powerful choice for many kinds of software projects, from enterprise systems to cross-platform games and mobile apps.

📝 Recap

• Start with console apps to focus on core C# skills.
• Move to web apps when ready to build interactive or multi-user projects.
