Figure 14-15. Enabling Edit and Continue in the project properties Modifying the Project The Edit and Continue feature is somewhat picky. There are some conditions under which it cannot work. One such condition is present in the Index action method of the HomeController class: the use of dynamic objects. To work around this, I have commented out the line that uses the view bag in the HomeController.cs class, as shown in Listing 14-6. Listing 14-6. Removing the ViewBag Call from the Index Method in the HomeController.cs File using System.Web.Mvc; namespace DebuggingDemo.Controllers { public class HomeController : Controller { public ActionResult Index() { int firstVal = 10; int secondVal = 0; int result = firstVal / secondVal; // This statement has been commented out //ViewBag.Message = "Welcome to ASP.NET MVC!"; } return View(result); 354
} } I need to make a corresponding change in the Index.cshtml view, as shown in Listing 14-7. Listing 14-7. Removing the ViewBag Call from the Index.cshtml File @model int @{ } Layout = null; Index The calculation result value is: @Model Editing and Continuing I am now ready for a demonstration of the Edit and Continue feature. Begin by selecting Start Debugging from the Visual Studio Debug menu. The application will be started with the debugger attached and run until it reaches the line where I perform the calculation in the Index method. The value of the second parameter is zero, which causes an exception to be thrown. At this point, the debugger halts execution, and the exception helper pops up (just like the one shown in Figure 14-13). Click the Enable editing link in the exception helper window. In the code editor, change the expression that calculates the value for the result variable, as follows: ... int result = firstVal / 2 ; ... I have removed the reference to the secondVal variable and replaced it with a numeric literal value of 2. Now select Continue from the Visual Studio Debug menu to resume execution of the application. The new value is used to generate the value for the result variable, producing the output shown in Figure 14-16. 355
