ECO IV is the latest release of "Enterprise Core Objects", an application framework that allows you to take applications from design to implementation in a much shorter time. ECO enables you to easily implement your applications as business classes rather than traditional data access. Instead of accessing the database directly your application will interact with the business classes you have designed using UML.

The free version of ECO for Visual Studio is much more than a trial version. There is no time limit, the only restriction is that the size of the model is limited to 12 classes. Applications built with the free version may be used for any purpose, including commercial use.
