Chapter 10. Error Handling, Debugging, and Tracing

Most code samples in this book don't include code intended to handle errors. It's not that error handling isn't important, but error handling can add complexity, and for the most part we've tried to keep the sample code as simple and clear as possible. Since you'll need to deal with errors in the real world of application programming, the first part of this chapter discusses the variety of techniques available in ASP.NET for handling errors, including custom error pages and structured exception handlinga new feature of Visual Basic .NET.

In addition to handling errors in ASP.NET applications, most developers want to figure out what's causing those errors. To that end, the latter part of this chapter discusses debugging using either the .NET Framework SDK debugger or Visual Studio .NET. The chapter also covers use of the ASP.NET trace feature to troubleshoot application problems.
