c# - Why does Application.Current == null in a WinForms application?

Why does Application.Current come out to null in a WinForms application? How and when is it supposed to be set?

I am doing:

 static class Program {
        /// <summary>
        /// The main entry point for the application.
        /// </summary>
        [STAThread]
        static void Main() {
            Application.Run(new MainForm());
        }
    }

Application.Current is Specific for WPF Application. Therefore when you are using WPF controls in WinForms Application you need to initialize instance of WPF Application. Do this in your WinForms Application.

if ( null == System.Windows.Application.Current )
{
   new System.Windows.Application();
}
