You can use either the Configuration Manager or the Project Manager to activate a build configuration.

1. Open the Configuration Manager by choosing ProjectConfiguration Manager.
2. On the Configuration Manager, select a configuration from the Configuration drop-down list. The list includes all the available configurations you have created in the project group, including the default configurations (Debug and Release). Selecting a configuration name causes the Applicable projects list to display the names of the projects that are associated with that configuration.
3. In Applicable projects, select the project or projects for which you want to activate the selected configuration. The Applicable projects list also includes the Active Configuration for each project.
4. To designate the selected Configuration name as the active configuration for the projects you've selected, click (Activate).

1. In the Project Manager, either double-click the name of a build configuration (such as Debug or Release) or right-click the name and select Activate from the context menu.
2. The name of the configuration changes to boldface to indicate that it is now the current active build configuration.
