The Win Application Framework (WAF) is a lightweight Framework that helps you to create well-structured XAML Applications in WPF and UWP. It supports you in applying various architectural patterns:

• Layered Architecture
• Modular Architecture
• Model-View-ViewModel pattern

How to get started?

• WAF comes with realistic real-world sample applications. Please have a look at them. See Sample Applications below.
• The Wiki provides further guidance.
• The fastest way to create a WAF project is by using the WAF Visual Studio Project Template. Please update the WAF NuGet packages to the latest stable version after project creation.

• *.Core (.NET Standard 2.0 and .NET Framework 4.6.1): Support for all .NET based applications.
• *.Wpf (.NET Framework 4.6.1): Extended support for Windows Presentation Foundation (WPF).
• [Experimental] .NET Core 3.0 with WPF: See Git Branch: netcoreapp3.0

System.Waf.Core

• Foundation
  • Cache: Provides support for caching a value.
  • Model: Base class that implements INotifyPropertyChanged.
  • ObservableListViewCore: Provide change notifications for sorting and filtering.
  • SynchronizingCollectionCore: Represents a collection that synchronizes all its items with the items of the specified original collection.
  • ThrottledAction: Throttling of multiple method calls to improve the responsiveness of an application.
  • ValidatableModel: Base class for a model that supports validation by implementing INotifyDataErrorInfo.
• Applications
  • (Async)DelegateCommand: An implementation of ICommand that delegates Execute and CanExecute.
  • RecentFileList: Most recently used (MRU) file list.
  • ViewModelCore: ViewModel base class with a simple approach to set the DataContext.

System.Waf.Wpf

• Foundation
  • DataErrorInfoSupport: Helper class for working with the legacy IDataErrorInfo interface.
• Applications
  • ApplicationInfo: Provides information about the running application.
  • ObservableListView: Same as ObservableListViewCore but using weak event handlers.
  • SynchronizingCollection: Same as SynchronizingCollectionCore but using weak event handlers.
  • ViewModel: ViewModel base class which sets the DataContext delayed via the Dispatcher.
• Presentation
  • DispatcherHelper: Implementation for DoEvents.
  • ResourceHelper: Helper methods to manage resources in WPF.
  • ValidationHelper: Support for data validation tracking.
  • Converters
    • BoolToVisibilityConverter: Converts a boolean value to and from a Visibility value.
    • InvertBooleanConverter: Inverts a boolean value.
    • NullToVisibilityConverter: Null condition to return the associated Visibility value.
    • StringFormatConverter: Converts an object into a formatted string.
    • ValidationErrorsConverter: Converts a ValidationError collection to a multi-line string error message.
  • Services
    • FileDialogService: Shows an open or save file dialog box.
    • MessageService: Shows messages via the MessageBox.

System.Waf.UnitTesting.Core

• AssertHelper: Assertion helper methods for expected exceptions, CanExecuteChanged event and PropertyChanged event.
• UnitTestSynchronizationContext: Synchronization context for unit tests that simulates the behavior of the WPF or Windows Forms synchronization context.
