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