Before we start the drag-and-drop extravaganza that the Designer enables, let's take a look at a slightly abbreviated version of the code generated by the WinForms application Wizard (available by right-clicking on the design surface and choosing View Code or by pressing F7):

Most of this code should be familiar, including the using statements at the top, the form class that derives from the Form base class, the static Main function inside a class providing the entry point to the application, and the call to Application.Run, passing an instance of the main form class. The only thing that's different from what we did ourselves is the call to InitializeComponent in the form's constructor to set the form's properties instead of doing it in the constructor itself. This is done so that the WinForms Designer, which we can use to design our form visually, has a place to put the code to initialize the form and the form's control. For example, dragging a button from the Toolbox onto the form's design surface will change the
