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