Info

Figure 2-9. The MVC Framework trying to find a default view This error message is quite helpful. It explains not only that MVC could not find a view for the action method, but it shows where it looked. This is another nice illustration of an MVC convention: views are associated with action methods by a naming convention. The action method is called Index and the controller is called Home and you can see from Figure 2-9 that MVC is trying to find different files in the Views folder that have that name. The simplest way to create a view is to ask Visual Studio to do it for you. Right-click anywhere in the definition of the Index action method in code editor window for the HomeController.cs file and select Add View from the pop-up menu, as shown in Figure 2-10. 38
Figure 2-10. Asking Visual Studio to create a view for an action method Visual Studio displays the Add View dialog, which allows you to configure the initial contents of the view file that will be created. Set View Name to Index (the name of the action method that the view will be associated with—another convention), set Template to Empty (without model), and leave the Create as a partial view and Use a layout page boxes unchecked, as shown in Figure 2-11. Don’t worry about what all of these options mean at the moment—I’ll explain all of the details in later chapters. Click the Add button to create the new view file. Figure 2-11.
