/* This sample demonstrates a designer that adds menu commands
to the design-time context menu for a component.
To test this sample, build the code for the component as a class library,
add the resulting component to the toolbox, open a form in design mode,
and drag the component from the toolbox onto the form.
The component should appear in the component tray beneath the form.
Right-click the component. The verbs should appear in the context menu.
