ReactiveProperty
ReactiveProperty provides MVVM and asynchronous support features under Reactive Extensions. Target framework is .NET 6.0+, .NET Framework 4.7.2 and .NET Standard 2.0.
ReactiveProperty is a very powerful and simple library.
This sample app's ViewModel code is as below:
public class MainPageViewModel
{
public ReactivePropertySlim<string> Input { get; }
public ReadOnlyReactivePropertySlim<string> Output { get; }
public MainPageViewModel()
{
Input = new ReactivePropertySlim<string>("");
Output = Input
.Delay(TimeSpan.FromSeconds(1))
.Select(x => x.ToUpper())
.ObserveOnDispatcher()
.ToReadOnlyReactivePropertySlim();
}
}
It is really simple and understandable (I think!). Because there are NOT any base classes and interfaces. Just has declarative code between Input property and Output property.
All steps are written in the "Getting Started" section in the ReactiveProperty documentation.
The concept of ReactiveProperty is simple that is a core class what name is ReactiveProperty[Slim]
, it is just a wrap class what has a value, and implements IObservable<T>
and INotifyPropertyChanged
, IObservable<T>
is for connect change event of the property value to Rx LINQ method chane, INotifyPropertyChanged
is for data binding system such as WPF, WinUI and MAUI.
And an important concept of ReactiveProperty is "Fun programing". ViewModel code with ReactiveProperty is very simple.
ViewModel's popular implementation:
public class AViewModel : INotifyPropertyChanged
{
public event PropertyChangedEventHandler PropertyChanged;
private string _name;
public string Name
{
get => _name;
set
{
_name = value;
PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(nameof(Name)));
// Update a command status
DoSomethingCommand.RaiseCanExecuteChanged();
}
}
private string _memo;
public string Memo
{
get => _memo;
set
{
_memo = value;
PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(nameof(Memo)));
// Update a command status
DoSomethingCommand.RaiseCanExecuteChanged();
}
}
// DelegateCommand is plane ICommand implementation.
public DelegateCommand DoSomethingCommand { get; }
public AViewModel()
{
DoSomethingCommand = new DelegateCommand(
() => { ... },
() => !string.IsNullOrEmpty(Name) && !string.IsNullOrEmpty(Memo)
);
}
}
Binding code:
<TextBlock Text="{Binding Name}">
<TextBlock Text="{Binding Memo}">
ViewModel's implementation using ReactiveProperty:
public class AViewModel
{
public ValidatableReactiveProperty<string> Name { get; }
public ValidatableReactiveProperty<string> Memo { get; }
public ReactiveCommandSlim DoSomethingCommand { get; }
public AViewModel()
{
Name = new ValidatableReactiveProperty<string>("",
x => string.IsNullOrEmpty(x) ? "Invalid value" : null);
Memo = new ValidatableReactiveProperty<string>("",
x => string.IsNullOrEmpty(x) ? "Invalid value" : null);
DoSomethingCommand = new[]
{
Name.ObserveHasErrors,
Memo.ObserveHasErrors,
}
.CombineLatestValuesAreAllFalse()
.ToReactiveCommand()
.WithSubscribe(() => { ... });
}
}
Binding code:
<TextBlock Text="{Binding Name.Value}">
<TextBlock Text="{Binding Memo.Value}">
It's very simple.
ReactiveProperty doesn't provide base class by ViewModel, which means that ReactiveProperty can be used together with another MVVM libraries such as Prism, Microsoft.Toolkit.Mvvm and etc.

Support
I'm not watching StackOverflow and other forums to support ReactiveProperty, so please feel free to post questions at Github issues. I'm available Japanese(1st language) and English(2nd language).
If too many questions are posted, then I plan to separate posting place about feature requests, issues, questions.
