I’ve spent much of the last three days with a client helping them figure out their domain model for their new system. What’s been a delight is using the VS 2005 Class Diagram to capture the ideas. Its been very easy to throw up on a projector and describe the relationships between the data. While we’re actually not using it to design the system, it was much easier to use the Class Diagram in VS 2005 than to fire up either Enterprise Architect(which I like a lot for UML/Database work) or Visio. Two Thumbs Up!
