ECO is a tool for creating model driven applications in Microsoft Visual Studio.

By making it faster to do it right than to cut corners, ECO is not only intended for developers that practice DDD (Domain Driven Design) as a matter of principle. It is equally suited for developers that just want to get the job done as fast as possible.

When ECO is used, the domain classes are defined in a model as class diagrams and state diagrams. ECO then generates both the database, the application code, and the O/R mapping, freeing developer creativity for less mundane tasks.
At runtime, ECO adds extensive framework support for tasks commonly needed on domain objects such as data binding, transaction handling and multilevel Undo/Redo.
ECO is particularly suited for agile processes such as SCRUM, since the model changes are immediately incorporated into the application. ECOs Database Schema Evolution ensures that existing data is not lost when the database is updated to match the new model saving further time on each iteration.
ECO can be used with all versions of Microsoft Visual Studio® 2008, except the express versions.
