    WinForms Getting Started Guide


    System.Windows.Forms is part of a standard Mono installation.

    WinForms Example

    As there are plenty of great articles and books on Windows Forms programming, the topic will not be covered in-depth. The following is just a simple Winforms program to test with.

    using System;
    using System.Drawing;
    using System.Windows.Forms;
    public class HelloWorld : Form
        static public void Main ()
            Application.Run (new HelloWorld ());
        public HelloWorld ()
            Button b = new Button ();
            b.Text = "Click Me!";
            b.Click += new EventHandler (Button_Click);
            Controls.Add (b);
        private void Button_Click (object sender, EventArgs e)
            MessageBox.Show ("Button Clicked!");

    If you save this code as hello.cs, you would compile it like this:

    csc hello.cs -r:System.Windows.Forms.dll

    The compiler will create “hello.exe”, which you can run using:

    mono hello.exe

    NOTE: on macOS you’ll have to wait around a minute the very first time you run this command.
