ReactiveUI packages are now signed by the dotnet foundation. Only builds from their infrastructure carry this seal. ReactiveUI uses Azure Dev Ops for our CI pipeline. Each platform has packages that extend the base ReactiveUI offerings for it's concerns. Installing the correct packages for the correct platform can be somewhat of a pain.

Platform	ReactiveUI Package	NuGet
.NET Standard	ReactiveUI
	ReactiveUI.Fody
.NET	ReactiveUI
	ReactiveUI.Fody
Unit Testing	ReactiveUI.Testing
WPF	ReactiveUI.WPF
WinUI	ReactiveUI.WinUI
MAUI	ReactiveUI.Maui
Windows Forms	ReactiveUI.WinForms
Xamarin.Forms	ReactiveUI.XamForms
Xamarin.Essentials	ReactiveUI
AndroidX (Xamarin)	ReactiveUI.AndroidX
Xamarin.Android	ReactiveUI.AndroidSupport
Xamarin.iOS	ReactiveUI
Xamarin.Mac	ReactiveUI
Tizen	ReactiveUI
Blazor	ReactiveUI.Blazor
Uno	ReactiveUI.Uno
Uno WinUI	ReactiveUI.Uno.WinUI
Avalonia	Avalonia.ReactiveUI
Any	ReactiveUI.Validation

Note ReactiveUI has packages for older .NET versions. Those packages are unlisted from NuGet and not supported, but you can still use them at your own risk to have ReactiveUI running on good old devices, such as Lumias, Surface Hubs, Windows XP, etc. See Delisting of versions before 8.0.0 from NuGet blog post for more info.

Example

The following isn't an exhausitve example, as some solutions will follow a different project structure or only use a subset of the platforms, but it should be enough to help with which packages to install on each platform project. Note non-platform specific packages (Reactive.Fody etc.) can be installed on any platform; Fody is often included in the core library to automatically generate the INotifyPropertyChanged boilerplate needed in the ViewModels.
