The Model-View-ViewModel can be used on all platforms. It intends to provide a clean separation between the user interface controls and their logic.
Benefits :* During the development process, developers and designers can work independently on their components. Designers can concentrate on the view, and if they are using Expression Blend, they can generate sample data. On the other hand, developers can work on the view model and model components.
* Developers create the unit tests for the view model and can create the model for the view.
* It is easy to redesign the UI of the application without touching the code because the view is implemented entirely in XAML. A new version of the view should work with the existing view model.
* If there is any existing representation of the model that binds the existing business logic, this can be difficult or risky to change. In this scenario, the view model acts as an adapter for the model classes and enable us to avoid making any major changes to the code of the model.
