• Fix event handler unsbscription leaks #450
• Fix deadlock on ReactivePropertyWpfScheduler #452

Fix

• Detach PropertyChanged events on Dispose #445

• Performance improvment for FilteredReadOnlyObservableCollection.

Add

• Add ReactivePropertyScheduler.SetDefaultSchedulerFactory method to set custom logic to create an IScheduler instance to dispatch events to UI thread.

Add

• Add ToReactivePropertySlimAsSynchronized extension method to INotifyPropertyChanged.

Fixes

• Issue #177, PR #178 The issue that the CollectionChanged event raised from ObservableCollection changes with ReadOnlyReactiveCollection

Add

• DisposePreviousValue extension method to IObservable<T>. Please see the issue #166 .

Changes

• ObserveProperty's behavior changed calling OnNext when PropertyChanged with an empty property name

This update is no feature changes.

• Fix #155 Some properties of Assembly file deleted in Ver 7.0.0

This is a major version up. There is a breaking change.
Please check the release note before updating it.

Breaking changes

• A ReadOnlyReactiveProperty created from a completed IObservable never call OnNext callback, just call OnCompleted callback. In version 6, it had called OnNext callback even if the source IObservable was finished.
  If you would like to subscribe a value completed ReadOnlyReactiveProperty, then please use OnCompleted callback like below:

  var completedReadOnlyReactiveProperty = Observable.Return("1").ToReadOnlyReactiveProperty();
  completedReadOnlyReactiveProperty.Subscribe(
    // OnNext callback. Because it was created from completed IObservable, the OnNext callback is never called in this case.
    x => DoSomething(x), 
    // OnCompleted callback, it will be called.
    () => DoSomething(completedReadOnlyReactiveProperty.Value);
  

• Separate the NuGet package to each platforms. The new packages are following:
  • ReactiveProperty
  • ReactiveProperty.Core
  • ReactiveProperty.WPF
  • ReactiveProperty.UWP
  • ReactiveProperty.XamarinAndroid
  • ReactiveProperty.XamariniOS

If you didn't use platform-specific features such as EventToReactiveCommand and EventToReactiveProperty on your code, then please use continuously ReactiveProperty package on v7.
If you used those features(It occurs as compile errors when updating the package), please add a package for the platform you are using.

And also, you have to change xmlns like below:

<!-- for WPF on .NET Framework on ReactiveProperty v6.2.0 or earlier -->
xmlns:rp="clr-namespace:Reactive.Bindings.Interactivity;assembly=ReactiveProperty.NET46"
<!-- for WPF on .NET Core on ReactiveProperty v6.2.0 or earlier -->
xmlns:rp="clr-namespace:Reactive.Bindings.Interactivity;assembly=ReactiveProperty.NETCore"

<!-- for WPF on .NET Core and Framework on ReactiveProperty v7.0.0 or lator -->
xmlns:rp="clr-namespace:Reactive.Bindings.Interactivity;assembly=ReactiveProperty.WPF"

Add

• Add ObserveValidationErrorMessage extension method to ReactiveProperty class. This is a shortcut for rp.ObserveErrorChanged.Select(x => x?.OfType<string>()?.FirstOrDefault()).

Perfomance improvement

ReactiveProperty and ReadOnlyReactiveProperty become 40% faster than v6.

Added

• Localization support and placeholder support for DataAnnotations. #137

Thank you for your feedback @onodera-sf and @soi013 !

Changes

• Update System.Reactive to 4.2.0 from 4.1.5
• Update Microsoft.Xaml.Behaviors.Wpf to 1.1.3 from 1.0.1
• IReactiveProperty interface became to inherit IReadOnlyReactiveProperty. Thank you @shanon-hs #131
• ReactiveProperty is officially support to WPF on .NET Core 3.0, because Microsoft.Xaml.Behaviors.Wpf became to support .NET Core.

This release is for fixing a binary breaking change at #109 and updating A value of AssemblyVersion is to correctly.

• Restore AsyncReactiveCommand(IObservable) Method #128
  Thank you @mimtari.

Changes

NuGet package

• Add a package dependency System.ComponentModel.Annotations to net461 and netcoreapp3.0. #125

New features

• Add BindTo extension methods to ReactivePropertySlim, ReadOnlyReactivePropertySlim and ReadOnlyReactiveProperty. #122 .
• Add Awaiter of ReactiveProperty and ReactivePropertySlim. #124

Thank you for your help @soi013, @s520 and @toras9000 .

Add to support WPF on .NET Core 3.0.

Changes

• Before this release, EventToReactiveCommand and EventToReactiveProperty couldn't be used on WPF on .NET Core 3.0. This release is supported those classes on WPF on .NET Core 3.0.

If you would like to use EventToReactiveCommand and EventToReactiveProperty, then please add Microsoft.Xaml.Behaviors.Wpf package to your project expricitlly.

There is a breaking change on WPF platform.

Breaking changes

• Dropped Blend SDK. Please use Microsoft.Xaml.Behaviors.Wpf package to use EventToReactiveCommand and EventToReactiveProperty.
  • Migration steps
    • Remove System.Windows.Interactivity and Microsoft.Expression.Interactions references.
    • If you are using System.Windows.Interactivity or Microsoft.Expression.Interactions namespace in your C# code, then change the namespaces to Microsoft.Xaml.Behaviors.
    • Replace Blend SDK's xml namespace(xmlns:i="http://schemas.microsoft.com/expression/2010/interactivity" and xmlns:ei="http://schemas.microsoft.com/expression/2010/interactions") in your XAML files to xmlns:i="http://schemas.microsoft.com/xaml/behaviors".

New features

• Add override using Func<IObservable<T>, IObservable<U>> to ToReactivePropertyAsSynchronized extension method.

// Usual method
var reactivePropertyInstance = source.ToReactivePropertyAsSynchronized(x => x.SomeProperty,
  x => convertLogic(x),
  x => convertBackLogic(x));

// New method
var reactivePropertyInstance = source.ToReactivePropertyAsSynchronized(x => x.SomeProperty,
  ox => ox.Select(x => convertLogic(x)),
  ox => ox.Select(x => convertBackLogic(x)));

It means you can filter value using Where method, like below:

var reactivePropertyInstance = source.ToReactivePropertyAsSynchronized(x => x.SomeProperty,
  ox => ox.Select(x => convertLogic(x)),
  ox => ox.Where(x => filterLogic(x)).Select(x => convertBackLogic(x)));

This version is for improvement of AsyncReactiveCommand.
