3. Create the web site in Visual Studio 2005 by using following step:
   • Open Visual Studio 2005. Open its File menu and click on New Web Site…
     
     
   • Select Asp.Net Web Site. In the location dropdown select File System rather than HTTP if you have already tested the other methods to configure your web applications to e debugged.
     
     
   • Browse to place your web site. Recommended path to place your web site is (C | OS Partition):\inetpub\wwwroot\
     
     
   • Select language VB/C# in which you want to script your web application.
