} Or you can disable any layout for a given view, like this: @{ } Layout = null; Debugging MVC Applications You debug an ASP.NET MVC application in exactly the same way as you debug an ASP.NET Web Forms application. The Visual Studio debugger is a powerful and flexible tool, with many features and uses. I can only scratch the surface in this book, but in the sections that follow I show you how to set up the debugger and perform different debugging activities on your MVC project. Preparing the Example Project To demonstrate using the debugger, I have created a new MVC project using the MVC project template, just so you can see how the default content and configuration is set up and the effect of the default theme that is applied to views. I called the new project DebuggingDemo, as shown in Figure 14-3. I have chosen the Individual User Accounts authentication option, which sets up a basic user security system. 342
Figure 14-3. Creating a new project using the MVC project template Click the OK button and Visual Studio will create the project and add the default packages, files, and folders that the MVC template includes. You can see how the files and settings added to the project are applied by starting the application, as shown in Figure 14-4. Figure 14-4. The effect of the additions made by the MVC project template There are some placeholder elements for the name of the application and branding, and some pointers to the MVC documents, NuGet, and some hosting options. The navigation bar at the top of the screen is the same kind I used for the SportsStore application and the layout has some responsive features. Change the width of the window to see the effect. Creating the Controller Visual Studio creates a Home controller as part of the initial project content, but I am going to replace the code that Visual Studio added with that shown in Listing 14-1.
