Release 7.8.0

Performance improvements for:

• PropertyChangedAsObservable
• CollectionChangedAsObservable
• CanExecuteChangedAsObservable
• ErrorsChangedAsObservable

This effects many methods that call those methods such as:

• ObserveProperty
• Observe(Add|Remove|Move|Replace|Reset)Changed
• Observe(Add|Remove|Move|Replace)ChangedItems
• ReadOnlyReactiveCollection
• ObserveElementProperty
• ObserveElementObservableProperty
• ObserveErrorInfo
• FilteredReadOnlyObservableCollection

Breaking changes

In the previous behavior, the method used SynchronizationCotext to automatically dispatch threads. This is due to the behavior of FromEvent and FromEventPattern in Reactive Extensions.
The new behavior does not automatically dispatch threads. It depends on which thread the event occurred in.

If you need to switch threads, please do so explicitly using the ObserveOn method.

Release 7.7.1

Performance improvement for FilteredReadOnlyObservableCollection.

Release 7.7.0

• Revert exception handling logic of ReadOnlyReactiveProperty/ReadOnlyReactivePropertySlim to same as version 6
  • Version 7.0 to 7.6: When throwing an exception on Rx method chain such as Select, ReadOnlyReactiveProperty ignore the exception.
  • After 7.7 : When throwing an exception on Rx method chain such as Select, ReadOnlyReactiveProperty throw the exception. This behavior is the same as version 6 or previous.

If you would like to ignore exceptions, please set ReactivePropertyMode.IgnoreException to mode argument to constructor or factory methods such as ToReadOnlyReactiveProperty method.

Release 7.6.1

Update dependency packages to latest:

• System.Reactive 4.4.1 -> 5.0.0
• Microsoft.Xaml.Behaviors.Wpf 1.1.19 -> 1.1.31
• System.ComponentModel.Annotations 4.7.0 -> 5.0.0

Release 7.6.0

Add

• Add ExecuteAsync method to AsyncReactiveCommand class. The method is to call all processes are added to a command object and to be able to wait to finish all processes with await keyword.

Release 7.5.1

Add

• Add nested property path support to ReactiveProperty.FromObject

Release 7.5.0

Add

• Add to support nested property path on ObserveProperty, ToReactivePropertyAsSynchronized and ToReactivePropertySlimAsSynchronized like following:

  obj.ObserveProperty(x => x.Child.Name);

• Add ObserveElementPropertyChanged, ObserveElementProperty and ObserveElementObservableProperty to IFilteredReadOnlyObservableCollection<T>.

Release 7.5.0-pre202010141113

Add

• Add to support nested property path on ObserveProperty, ToReactivePropertyAsSynchronized and ToReactivePropertySlimAsSynchronized like following:

  obj.ObserveProperty(x => x.Child.Name);
