To expose all properties for a selected class
Right-click on the class row in the Classes table and then select the Expose Properties for Selected Class 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 that class 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 for that class 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.
