' 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.
