View Location + IViewFor

View Location is a feature of ReactiveUI that allows you to associate Views with ViewModels and set them up Automagically.

ViewModelViewHost

The easiest way to use View Location is via the ViewModelViewHost control, which is a View (on Cocoa, a UIView/NSView, and on XAML-based platforms a Control) which has a single ViewModel property. When the ViewModel property is set, View Location looks up the associated View and loads it into the container. ViewModelViewHost is great for lists - so much so, that if you Bind to ItemsSource on XAML-based platforms and don't set a DataTemplate, one gets configured that just uses ViewModelViewHost.

<ListBox x:Name="ToasterList" />

// Now ListBox automatically gets a DataTemplate
this.OneWayBind(ViewModel, vm => vm.ToasterList, v => v.ToasterList.ItemsSource);

Registering new Views

To use View Location, you must first register types, via Splat's Service Location feature.

Locator.CurrentMutable.Register(() => new ToasterView(), typeof(IViewFor<ToasterViewModel>));

View Location internally uses a class called ViewLocator which can either be replaced, or the default one used. The ResolveView method will return the View associated with a given ViewModel object.
