ECO is the core engine for all MDriven applications.

It's the engine that, given a UML model and a Persistence Mapper, will help any .net application handle the objects of that model in memory. ECO will, via the Persistence Mapper, help dehydrate or hydrate objects from persistent storage, ie a database.

ECO is also the name of a Visual Studio Plugin that brings ECO, Modlr, Derived Code, Derived DB scripts, and Database Evolution to Visual Studio.

ECO is UI-agnostic – it does, however, contain parts that help with asynchronous access to persistence storage (good for WPF and a must for Silverlight). It contains parts for serializing a complete object graph into a cache (very useful for ASP.NET and MVC), and also contains parts that make it easy to bring objects from the model to a format that makes it easy to data bind to WindowsForms, WPF, Silverlight, ASP.NET and ASP MVC.
