You can include any constant defined in a JADE class in a C# exposure.
To toggle the display of constants
Right-click on any row in the Classes table and then select the Show Constants command from the popup menu that is displayed.
A check mark is displayed when constants are displayed in the Features pane. (When constants are first displayed, they are not selected for inclusion in the C# exposure.) All constants are then displayed in a green font or are removed from display in the Features pane.
