// The example is from the book "Windows Forms in Action 2-nd edition 2012" coolcsn
// csc /t:exe /out:MyForm.exe *.cs
using System; // must be first

// the program works without the following line
// The following line of the program simply sets the version number for the program to 1.0, matching the section number of the book.
// You can verify this by right-clicking the myform.exe file, selecting Properties, and then clicking the Version tab.
