How to: Hide Solution Folders
If you are working with a solution that contains numerous projects, you can hide one or more Solution Folders so that you can work more easily in Solution Explorer. When a Solution Folder is hidden, the Solution Folder and all the projects and items that it contains are not visible in Solution Explorer. However, the projects are still available in the solution. For example, hidden projects can be included in builds, referenced by other projects that are building, and updated when you get the latest version of the solution from source control. Alternatively, you can make projects temporarily unavailable within a solution. For more information, see How to: Unload the Projects in a Solution Folder.
