Figure 2.1 Components of the initial Visual Studio .NET window that relate to the discussion in this chapter. The exact placement of some of these windows may vary.
As a way to structure our discussion, this chapter as well as subsequent chapters will use the Action-Result table format described in the introduction to present the steps required to create the sample code discussed in each chapter. These tables provide numbered instructions for the task, including the actions to perform and the result of these actions.
In this section we will create a Visual Studio project for our application, compile and run this application from within Visual Studio, and look at the source code generated by Visual Studio in contrast to the program we wrote in section 1.1.
2.1.1Creating a project
To begin, let’s create a Visual Studio project called “MyPhotos” for our new application. This application will duplicate the functionality presented in section 1.1. The

Visual Studio .NET has a lot of information and a ton of features. We will cover some features in this section, and others as we develop our application. On the right side of the Visual Studio window, you will see the Solution Explorer window. This window shows the contents of the current solution, namely the projects in the solution and files in these projects.
Visual Studio uses projects and solutions to manage application development. Conceptually, a project is a collection of files that produce a .NET application, such as a library (.dll) or executable (.exe). A solution is a collection of projects that are grouped together for development or deployment purposes. When a solution has only one project, the two words are somewhat equivalent.
The MyPhotos solution is stored on disk in a file called “MyPhotos.sln.” This solution holds a single project called MyPhotos, stored in the C# project file “MyPhotos.csproj.” The Solution Explorer window shows the MyPhotos solution containing the MyPhotos project. This project displays four items:
•References—the list of assemblies referenced by the project. These are provided to the compiler using the /references switch we saw in chapter 1. You can expand this entry to see the default list of assemblies for the project, or wait until chapter 5 where we add an assembly to this list.
•App.ico—the icon for the application. We will discuss icons in chapter 12.
