Alan Wills has created a new sample that pulls together several of the capabilities of our Visualization and Modeling SDK.  The sample illustrates:

• How to associate data with any UML element by using References.
• How to add decorators to UML elements
• How to add rules to respond to changes in a UML model
• How to define menu commands for UML
• How to handle the user dragging various kinds of object onto a UML diagram:
  • Project Items from Solution Explorer
  • Files from Windows Explorer
  • Shapes from other UML diagrams
