ViewModels
The View Model is a part of MVVM applications responsible for the interaction between the two other parts: Model and View.
The DevExpress MVVM Framework provides several base classes, which you can use for deriving your View Models for the easy implementation of bindable properties, validation, commands, consuming services, and for implementing interaction between View Models.
Another powerful feature of the DevExpress MVVM Framework is the POCO mechanism, which simplifies and accelerates the View Model development process.
