ReactiveUI.SourceGenerators

Compile-time code for ReactiveUI. No reflection. Trim and NativeAOT safe.

</div>

Two families of Roslyn source generators that work together:

Attribute generators Binding generators
Package ReactiveUI.SourceGenerators ReactiveUI.Binding (and platform packages)
You write [Reactive], [ReactiveCommand], [IViewFor] WhenChanged, Bind, ToProperty, [ObservableAsProperty]
You get Properties, commands, views, collections Observations and bindings, with no expression trees
Guide Attribute generators Binding reference

Quick start

Attributes. Mark a field. The property, its change notification and the command are written for you.

public partial class LoginViewModel : ReactiveObject
{
    [Reactive] private string _userName = "";

    [ReactiveCommand]
    private void SignIn() { }
}

Binding. Name the path as a lambda. The generator writes the code that attaches to each link of it.

IObservable<string> city = viewModel.WhenChanged(x => x.Address.City);

view.OneWayBind(viewModel, x => x.UserName, v => v.NameLabel.Text);

Install

dotnet add package ReactiveUI.SourceGenerators   # attribute generators
dotnet add package ReactiveUI.Binding            # binding generators, no System.Reactive
dotnet add package ReactiveUI.Binding.Reactive   # binding generators on System.Reactive

Reference one binding runtime package, not both. Add PrivateAssets="all" to ReactiveUI.SourceGenerators.

Packages

Package Purpose
ReactiveUI.SourceGenerators Attribute generators
ReactiveUI.Binding, ReactiveUI.Binding.Reactive Binding runtime, generator and analyzer
ReactiveUI.Binding.Wpf, .WinForms, .Maui, .Avalonia, .Uno Platform property observation and view thread routing
*.Reactive platform packages The same, for System.Reactive apps

Requirements

Attribute generators Binding generators
Language C# 12 C# 7.3 for generated code; interceptors need C# 11
Compiler Roslyn 4.8 or later Roslyn 4.8 or later; interceptors need 4.13
Runtime .NET 10 and 11, .NET Framework 4.7 to 4.8.1 The same

Examples

Every example runs and prints what it does.

Example Shows
index Your first binding
observing WhenChanged, WhenAny, WhenAnyValue, WhenAnyObservable
bindings One-way, two-way, command and interaction bindings
properties ToProperty and [ObservableAsProperty]
converters Built-in type converters
custom-converters Writing your own converters
mechanisms How a property reports a change
views The view locator and IViewFor<T>
threading Which thread a binding writes on
xaml Controls named in MAUI and Avalonia XAML
sourcegenerators Binding to members the attribute generators write
unsafe Run-time expressions
setup Configuration, analyzer and NativeAOT
Execute The attribute generators in use
ToPropertyVerification ToProperty on every runtime target
PlatformBindingsVerification ToProperty feeding real WPF, WinForms and MAUI controls
