DevExpress MVVM Framework - Use DevExpress Services with a Dependency Injection

This example illustrates how to use the NavigationService with Dependency Injection.

Use the AttachServiceBehavior to register services that require a specific view (such as FrameNavigationService, TabbedDocumentUIService, WizardService):

<dxwui:NavigationFrame>
    <dxmvvm:Interaction.Behaviors>
        <common:AttachServiceBehavior Service="{Binding NavigationService}"/>
    </dxmvvm:Interaction.Behaviors>
</dxwui:NavigationFrame>

Inject the service in the ViewModel's constructor:

public class MainViewModel {
    public INavigationService NavigationService { get; }

    public MainViewModel(INavigationService navigationService) =>
        NavigationService = navigationService;
}
