Debugging ASP.NET Web applications is similar to debugging a Windows Form or any other Windows application because both kinds of applications involve controls and events. However, there are also basic differences between the two kinds of applications:

  • Keeping track of state is more complex in a Web application.

  • In a Windows application, the code to be debugged is mostly in one location; in a Web application, the code can be on the client and on the server. While ASP.NET code is all on the server, there might also be JavaScript or Visual Basic code on the client.
