static void Main()

Application.Run(new Form1());

public Form1()

// Create the LinkLabel.

this.linkLabel1 = new System.Windows.Forms.LinkLabel();

// Configure the LinkLabel's location.

this.linkLabel1.Location = new System.Drawing.Point(34, 56);

// Specify that the size should be automatically determined by the content.

 this.linkLabel1.AutoSize = true;

// Add an event handler to do something when the links are clicked.

this.linkLabel1.LinkClicked += new
System.Windows.Forms.LinkLabelLinkClickedEventHandler(this.linkLabel1_LinkClicked);

// Set the text for the LinkLabel.

this.linkLabel1.Text = "Visit Microsoft";

// Set up how the form should be displayed and add the controls to the form.
