Project items can be files, references to libraries, data connections, and folders that are within the project container. Some items represent a physical item you can locate in storage. Other items are links and represent pointers to other items that may reside within a service, module, or other component.
However, most of your work is likely to be on the files you use to determine the parts of your application. How these files are managed within a project is determined by the project itself. Solution Explorer displays the file or set of files needed to develop that item. For more information about how projects manage items, see Item Management in Projects. For information about item management within a specific project type, see the documentation for the language or project type that is of interest to you.
All Visual Studio development products provide a number of pre-defined item templates. You can use one of the many templates to create the items that you might need to develop your application, class, control, or library. For example, if you chose to create a Windows form, the project offers a Windows form item for you to add and customize. Similarly, if you chose to create a Web application, the project offers a Web form item. For more information about project types and templates for your language, see Add New Item Dialog Box.
