So here's three complete programs which demonstrate how I would go about evolving some code including a main component called MyThing. The initial implementation would be very direct and very concrete, the next implementation would factor out an interface, and the final implementation would implement MyThing in a full-blown extensible framework. All versions support construction via a MyThing.Create() factory method, thus "construction idioms".
| Example program | Note |
|---|---|
| Take Zero | concrete implementation |
| Take One | introduce interface |
| Take Two | extensible framework |
