I have just started learning C#.

Can anyone explain the technical differences between a .Net desktop application and a web application?.

I mean for example, if I have a simple HelloWorld application using a WinForm, what are the steps required to change that into a HelloWorld web application?

    There’s no real way to make a “fair comparison” as the two really are like “chalk and cheese”. A desktop application has one “entry point”, running the executable whereas a web application has many, each .aspx page that you’ve created.

    There’s no “easy” way to convert a “Hello World” application as the UI/presentation models are so completley different. A classic console application is entirely written in code using Console.WriteLine, whereas a webforms application that says “Hello World” can be written entirely in asp.net markup.

    An asp.net “Hello World” application can be as simple as a file called default.aspx containing:

    <%@ Page Language="C#" AutoEventWireup="true"%>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
    <title></title>
</head>
<body>
    <form id="form1" runat="server">
Hello, world!
    </form>
</body>
</html>

    Whereas the console/desktop application equivalent is:

    using System;
namespace ConsoleHelloWorld
{
    class Program
    {
        static void Main(string[] args)
        {
            Console.Write("Hello World");
        }
    }
}
