doesn’t use code-behind?
Ans) Start the DbgClr debugger that comes with the .NET Framework SDK, open the file containing the code you want to debug, and set your breakpoints. Start the ASP.NET application. Go back to DbgClr, choose Debug Processes from the Tools menu, and select aspnet_wp.exe from the list of processes. (If aspnet_wp.exe doesn’t appear in the list, check the “Show system processes” box.) Click the Attach button to attach to aspnet_wp.exe and begin debugging.
