To close a project, select it in the Project Explorer and click on the menu. To close all projects except the selected one and its related projects, right-click the selected project and click Close Unrelated Projects on the context menu.
To reopen a closed project, select it in the Project Explorer and click on the menu.
If necessary, the Project Explorer can be customized to hide closed projects:
toolbar button.


To reopen a closed project hidden from the Project Explorer, customize the Project Explorer settings to show closed projects. Then reopen the closed project as described above.
