This repository contains 4 sample WPF/MVVM applications that implement different techniques to deal with fast changing properties in the Model.

1. Project Problem keeps the ViewModel synchronized with the Model
2. Project Solution1 uses Reactive Framework's Sample() to reduce the frequency
3. Project Solution2 uses a DispatcherTimer in the ViewModel
4. Project Solution3 attaches to CompositionTarget.Rendering

They all use the same Model class from the Common project.
