Introduction to Solutions, Projects, and Items
Visual Studio provides two containers to help you efficiently manage the items that are required by your development effort, such as references, data connections, folders, and files. These containers are called solutions and projects. Also, Visual Studio provides Solution Folders to organize related projects into groups and then perform actions on those groups of projects. Solution Explorer, an interface for viewing and managing these containers and their associated items, is part of the integrated development environment (IDE).
Solutions and projects contain items that represent the references, data connections, folders, and files that you need to create your application. A solution can contain multiple projects and a project typically contains multiple items. These containers enable you to take advantage of the IDE in the following ways:
Manage settings for your solution as a whole or for individual projects.
Use Solution Explorer to handle the details of file management while you focus on items that make up your development effort.
Add items that are useful to multiple projects in the solution or to the solution without referencing the item in each project.
Work on miscellaneous files that are independent from solutions or projects.
Items can be files and other parts of your project such as references, data connections, or folders. In Solution Explorer, items can be organized in the following ways:
As project items, which are items that compose your project, such as forms, source files, and classes within a project in Solution Explorer. The organization and display depends on the project template you select as well as any modifications you make.
As solution items for files that are applicable to your solution as a whole in the Solution Items folder of Solution Explorer.
As miscellaneous files for files that are not associated with either a project or a solution and that can be displayed in a Miscellaneous Files folder.
