1、console

namespace MyNamespace
{
    class MyClass
    {
        static void Main(string[] args)
        {
            Console.WriteLine("Hello,World!");        
        }
    }
}

2、WPF

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using System.Windows.Navigation;
using System.Windows.Shapes;

namespace WpfApp1
{
    /// <summary>
    /// Interaction logic for MainWindow.xaml
    /// </summary>
    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();
        }

        private void buttonSayHello_Click(object sender, RoutedEventArgs e)
        {
            textShowHello.Text = "Hello,World!";
        }
    }

<Window x:Class="WpfApp1.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
        xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
        xmlns:local="clr-namespace:WpfApp1"
        mc:Ignorable="d"
        Title="MainWindow" Height="450" Width="800">
    <Grid>
        <Grid.Background>
            <LinearGradientBrush EndPoint="0.5,1" StartPoint="0.5,0">
                <GradientStop Color="Black"/>
                <GradientStop Color="#FF1DC1D6" Offset="1"/>
            </LinearGradientBrush>
        </Grid.Background>
        <TextBox x:Name="textShowHello" HorizontalAlignment="Left" Margin="10,9,0,0" TextWrapping="Wrap" VerticalAlignment="Top" Width="783" RenderTransformOrigin="0.5,0.5" Height="33">
            <TextBox.CaretBrush>
                <LinearGradientBrush EndPoint="0.5,1" StartPoint="0.5,0">
                    <GradientStop Color="Black"/>
                    <GradientStop Color="#FFE91F1F"/>
                </LinearGradientBrush>
            </TextBox.CaretBrush>
            <TextBox.RenderTransform>
                <TransformGroup>
                    <ScaleTransform/>
                    <SkewTransform/>
                    <RotateTransform Angle="-0.11"/>
                    <TranslateTransform/>
                </TransformGroup>
            </TextBox.RenderTransform>
        </TextBox>
        <Button x:Name="buttonSayHello" Content="click me" HorizontalAlignment="Left" Margin="0,62,0,0" VerticalAlignment="Top" Width="790" Height="31" Click="buttonSayHello_Click"/>

    </Grid>
</Window>

3、windows forms

namespace WinFormsApp
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void textBox1_TextChanged(object sender, EventArgs e)
        {

        }

        private void buttonSayHello_Click(object sender, EventArgs e)
        {
            textBoxSayHello.Text = "Hello,World!";
        }
    }
}

4、ASP.NET Web Forms

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="default.aspx.cs" Inherits="WebApplication2._default" %>

<!DOCTYPE html>

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
    <title></title>
</head>
<body>
    <h1>Hello,World!</h1>
</body>
</html>

5、ASP.NET MVC(Model-View-Controller)

@{
    <h2>Hello,World!</h2>
}
