selecting Delete Breakpoint from the pop-up menu. When you start the debugger, the application will run until the exception is thrown, at which point the exception helper pop-up will appear, as shown in Figure 14-13. Figure 14-13. The exception helper The exception helper gives you details of the exception. When the debugger breaks on an exception, you can inspect the application state and control execution, just as when a breakpoint is hit. Using Edit and Continue An interesting Visual Studio debugging feature is called Edit and Continue. When the debugger breaks, you can edit your code and then continue debugging. Visual Studio recompiles your application and re-creates the state of your application at the moment of the debugger break. Enabling Edit and Continue 352
I need to make sure that Edit and Continue is enabled in two places: In the Edit and Continue section of the Debugging options (select Options from the Visual Studio Tools menu), make sure that Enable Edit and Continue is checked, as shown in Figure 14-14. Figure 14-14. Enabling Edit and Continue in the Options dialog box In the project properties (select DebuggingDemo Properties from the Visual Studio Project menu), click the Web section and ensure that Enable Edit and Continue is checked, as shown in Figure 14-15. 353
