Debugging and tracing let you diagnose and fix problems with the Web application, and are primarily intended to be used during development. Enabling debugging causes the pages in the Web site to be compiled with information that the .NET Framework or the Microsoft Visual Studio debugger can use to step through your code. Enabling tracing causes pages to generate information about individual Web requests, the HTTP headers that are sent with the requests, the state of controls on the page, and other details about page processing.
