What is ReactiveUI?

ReactiveUI is a composable, cross-platform model-view-viewmodel framework for all .NET platforms that is inspired by functional reactive programming, which is a paradigm that allows you to abstract mutable state away from your user interfaces and express the idea around a feature in one readable place and improve the testability of your application.

There has been an excellent book written by our Alumni maintainer Kent Boogart.

NuGet Packages

Install the following packages to start building your own ReactiveUI app. <b>Note:</b> some of the platform-specific packages are required. This means your app won't perform as expected until you install the packages properly. See the <a href="https://reactiveui.net/docs/getting-started/installation/">Installation</a> docs page for more info.

Migration from Xamarin and .NET 8 MAUI

Xamarin Users

As of May 2024, Microsoft ended support for Xamarin per their support policy. ReactiveUI has removed support for legacy Xamarin platforms in favor of modern .NET MAUI. For Xamarin projects:

  • Xamarin.Forms β†’ Migrate to MAUI and use ReactiveUI.Maui
  • Xamarin.Android β†’ Migrate to MAUI Android or use ReactiveUI.AndroidX for native Android
  • Xamarin.iOS/Mac β†’ Migrate to MAUI iOS/Mac Catalyst

For guidance on migrating from Xamarin to MAUI, see the official migration documentation.

MAUI .NET 8 Users

ReactiveUI now requires .NET 9 for MAUI platforms. Update your projects to:

  • net9.0-android (was net8.0-android)
  • net9.0-ios (was net8.0-ios)
  • net9.0-maccatalyst (was net8.0-maccatalyst)
  • net9.0-windows (was net8.0-windows)

Note: Non-MAUI net8.0 library targets remain fully supported.

This is how we use the donations:

  • Allow the core team to work on ReactiveUI
  • Thank contributors if they invested a large amount of time in contributing
  • Support projects in the ecosystem
