To expose all properties in all classes included in the C# exposure
Right-click on any row in the Classes table and then select the Expose Properties for All Classes command from the popup menu that is displayed.
This command does not automatically add methods or constants to the C# exposure, even if the Show Methods or Show Constants option is checked. (For details, see "Toggling the Display of Methods" or "Toggling the Display Constants", later in this chapter.)
All properties in the classes selected on the Select Classes sheet of the wizard are then exposed for inclusion in the C# exposure; that is, each property check box in the Features pane is checked, indicating that the properties will be generated in the C# class library.
You can tailor the property selection by unchecking the check box of any property that you want to exclude from the exposure.
