Ensure that you install ReactiveUI.WPF into your application.
Your viewmodels should inherit from ReactiveObject
Use IActivatableViewModel and WhenActivated for lifecycle
- https://reactiveui.net/api/reactiveui/IActivatableViewModel/
- https://reactiveui.net/docs/handbook/when-activated/
Keep references to your subscriptions
Use disposables to manage lifetime, scope and resources:
Don't use eventhandlers, use the extension methods shipped in reactiveui.events.wpf instead
Use your normal WPF concepts that you would usually use in WPF development. There's also some extension methods which will make your life easier
