A MVVM framework that integrates with the Reactive Extensions for .NET to create elegant, testable User Interfaces that run on any mobile or desktop platform. This is the Source Generators package for ReactiveUI
$ dotnet add package ReactiveUI.SourceGeneratorsUse source generators to generate ReactiveUI objects.
Not taking public contributions at this time
These Source Generators were designed to work in full with ReactiveUI V19.5.31 and newer supporting all features, currently:
Versions older than V19.5.31 to this:
Typically properties are declared like this:
private string _name;
public string Name
{
get => _name;
set => this.RaiseAndSetIfChanged(ref _name, value);
}
Before these Source Generators were avaliable we used ReactiveUI.Fody.
With ReactiveUI.Fody the [Reactive] Attribute was placed on a Public Property with Auto get / set properties, the generated code from the Source Generator and the Injected code using Fody are very similar with the exception of the Attributes.
[Reactive]
public string Name { get; set; }
Similarly, to declare output properties, the code looks like this:
public partial class MyReactiveClass : ReactiveObject
{
ObservableAsPropertyHelper<string> _firstName;
public MyReactiveClass()
{
_firstName = firstNameObservable
.ToProperty(this, x => x.FirstName);
}
public string FirstName => _firstName.Value;
private IObservable<string> firstNameObservable() => Observable.Return("Test");
}
With ReactiveUI.Fody, you can simply declare a read-only property using the [ObservableAsProperty] attribute, using either option of the two options shown below.
[ObservableAsProperty]
public string FirstName { get; }

public partial class MyReactiveClass : ReactiveObject
