-- My First Project !! --

Question

Hi All,
I just started to design a SilverLigt Project. I designed my MainPage.xaml (A Button and a Label) and I wrote the Codes in Button's Click Event. But I dunno why The Internet Explorer Cannot Show the SLExampleTestPage.aspx (SLExample is my Projects Name) .. Is there anyone to help me ??  
<< Codes >>
Private void Button_Click(object sender, RoutedEventArgs e)
{
     Label1.Content=" Hello World :) ";
}
