International Settings, Environment, Options Dialog Box
The International Settings page allows you to change the default language when you have more than one language version of the integrated development environment (IDE) installed on your machine. You can access this dialog box by selecting Options from the Tools menu and then choosing International Settings from the Environment folder. If this page does not appear in the list, select Show all settings in the Options dialog box.
The options available in dialog boxes, and the names and locations of menu commands you see, might differ from what is described in Help depending on your active settings or edition. To change your settings, choose Import and Export Settings on the Tools menu. For more information, see Customizing Development Settings in Visual Studio.
