UModel IDE plug-ins must implement the IUModelPlugIn interface. The code below shows a simple implementation of this interface. It adds a menu item and a separator (available with UModel) to the Edit menu. Clicking the menu item will display a message box with the text "Hello, World!".
| Note: | Since this sample displays a message box, ensure that your C# project also references System.Windows.Forms. To do this, right-click References in Solution Explorer, select Add Reference, and browse for the System.Windows.Forms assembly). |
