Installation

ReactiveUI packages are signed by the .NET Foundation. Install platform-specific packages alongside the core ReactiveUI package as needed.

Platform	ReactiveUI Package	NuGet
.NET (Core libs)	ReactiveUI
Unit Testing	ReactiveUI.Testing
WPF	ReactiveUI.WPF
WinUI	ReactiveUI.WinUI
MAUI	ReactiveUI.Maui
Windows Forms	ReactiveUI.WinForms
Xamarin.Forms (legacy)	ReactiveUI.XamForms
AndroidX (legacy Xamarin)	[ReactiveUI.AndroidX][DroDoc]
Blazor	ReactiveUI.Blazor
Uno	ReactiveUI.Uno
Uno WinUI	ReactiveUI.Uno.WinUI
Avalonia	Avalonia.ReactiveUI
Validation	ReactiveUI.Validation

Note: Xamarin platforms are considered legacy. For new applications, prefer .NET (WPF/WinForms/WinUI), MAUI, Avalonia, or Uno. Fody-based packages are legacy; prefer ReactiveUI.SourceGenerators for code generation.
