The computer hangs when debugging an ASP.NET webform

I start learning ASP.NET few days. I don't know why my computer hangs when I debug my very simple application? My computer hangs, not开发者_StackOverflow only IDE hangs? Please help me!

Is the application added as a virtual directory to IIS? Maybe adding the application to IIS will help remedy it if you are using the local web server. Also, try checking the application log in the event viewer for any error statements, see if the tool you are using is logging errors.

We need more info about what IDE you are using, the .NET framework version?
