ProjectConfiguration Manager 

The Configuration Manager is composed of left-hand pane and a right-hand pane, and at the top is a drop-down Configuration selection list and a set of six buttons. You can use the buttons and the context menu commands of the Configuration Manager to perform any of the following tasks:

• Designate the active build configuration for a project.
• Create a new build configuration based on a selected configuration for one or more projects
• Apply an option set to the current selected build configuration(s)
• Save the current option set to disk as an .optset file
• Delete configurations
• Edit option sets
• Remove referenced option sets from one or more projects

Button Help: The six buttons at the top display customized tool-tip help that describes exactly what the button will do if you click it. Move the mouse over the button to display the current tool tip. For example:  

Make <selected_configuration> the active configuration for
                                              selected projects

The two panes of the Configuration Manager have the following functions: 

• The left-hand pane displays the current projects and the active configuration for each project. The All tab lists all the projects and project groups that have the selected configuration. To enable the buttons, you need to select one or more projects from this list.
• The right-hand pane displays the option values of a selected option set that has been applied by reference to the currently selected configuration. The right-hand pane is blank and only the All tab is present for a configuration that has no option sets that were applied by reference.

Right-pane Help: Two lines at the top of the right-hand pane display help cues. For example, the following help message is displayed when the selected project has no option sets (and thus nothing can be displayed in the right-hand pane):  

Configuration <name> has no referenced option sets.

After you select a configuration that has one or more referenced option sets, the following help message is displayed to direct you to select a tab to display the option set::

No option set selected. Click on a tab to select an option set.
