是什么让一个应用程序控制台或Windows窗体应用程序？

[Visual Studio 2008中]

[Visual Studio 2008]

我创建的控制台应用程序一个新的项目，并修改它看起来是这样的：

I created a new project for console application and modified it to look like this:

class Program
{
    static void Main (string[] args) {
        Thread.Sleep (2000);
    }
}

然后，我创建了另一个项目的Windows窗体应用程序，并修改了它：

Then I created another project for Windows Form application and modified it:

static class Program
{
    //[STAThread] commented this line
    static void Main (string[] args) { //Added args
        //Commented following lines
        //Application.EnableVisualStyles ();
        //Application.SetCompatibleTextRenderingDefault (false);
        //Application.Run (new Form1 ()); commented this line
        Thread.Sleep (2000);
    }
}

现在我既没有书面Console功能（Console.Write等）的第一个应用程序或我都写在第二个相关的操作形式。看起来与我。

Now I have neither written Console functions (Console.Write etc.) in first application nor I have written forms related operations in second one. Looks identical to me.

不过首次申请显示黑色窗口和第二个没有显示任何东西。是什么让这样的工作？

Still first application shows BLACK window and second one doesn't show anything. What makes it work like this?
