MvvmFx

Model-View-ViewModel application framework and library for WPF, Surface, and Silverlight

MvvmFx makes it easy to implement M-V-VM and leverage pre-existing functionality and code for common situations. It's developed in C#.

It contains a set of base classes and functionality for rapidly creating applications using the M-V-VM approach to application architecture.

It targets both WPF and Silverlight, and contains specific classes for supporting Microsoft Surface development.

It favours a compositional approach over inheritance - the base ViewModel classes are very lightweight and additional behaviors are exposed via composition

It provides the following functionality:

• Light-weight Base ViewModel and ViewModelCollection classes
• Support for observing ViewModel changes via the ObservableViewModel and ObservableViewModelCollection classes.
• Easy support for binding to selectable collections via the SelectableViewModel and SelectableCollection classes.
• Several implementations of ICommand - ViewModelCommand, RoutedViewModelCommand, ActionCommand, DelegateCommand.
• CommandHandler class for handling the execution of commands at the level of the views.
• Validation rules engine - based on the delegate approach to validation rules in Rocky Lhotka's CSLA framework.
• Out-the-box support for process-oriented GUI's such as wizards or page workflows, via the ProcessManagement namespace.
• Change tracking support - automatically track when a ViewModel or one of its child objects is modified.
• Classes to load and save ViewModel objects to/from their corresponding model objects.
• Factory classes for creating ViewModel objects to encapsulate their hydration from model objects.
• Support for stateful Surface applications using a state-engine approach.
• Several useful ValueConverters for common scenarios
• Many useful Helper classes for common scenarios.
• Attached properties for:
  • Binding Silverlight controls to commands
  • Binding WPF RoutedEvents to commands
  • Getting DesignTime text in Silverlight - like the FallbackValue property in WPF.
• DataTemplateSelector for Silverlight
• Several Sample projects and examples to demonstrate how to use the framework.
