How to use

App.xaml.cs

public class App : PrismApplication
{
    public static bool IsSingleViewLifetime =>
        Environment.GetCommandLineArgs()
            .Any(a => a == "--fbdev" || a == "--drm");

    public static AppBuilder BuildAvaloniaApp() =>
        AppBuilder
            .Configure<App>()
            .UsePlatformDetect();

    public override void Initialize()
    {
        AvaloniaXamlLoader.Load(this);
        base.Initialize();
    }

    protected override IAvaloniaObject CreateShell()
    {
        if (IsSingleViewLifetime)
            return Container.Resolve<MainControl>(); // For Linux Framebuffer or DRM
        else
            return Container.Resolve<MainWindow>();
    }

    protected override void ConfigureModuleCatalog(IModuleCatalog moduleCatalog)
    {
        // Register modules
        moduleCatalog.AddModule<Module1.Module>();
        moduleCatalog.AddModule<Module2.Module>();
        moduleCatalog.AddModule<Module3.Module>();
    }

    /// <summary>Called after <seealso cref="Initialize"/>.</summary>
    protected override void OnInitialized()
    {
      // Register initial Views to Region.
      var regionManager = Container.Resolve<IRegionManager>();
      regionManager.RegisterViewWithRegion(RegionNames.ContentRegion, typeof(DashboardView));
      regionManager.RegisterViewWithRegion(RegionNames.SidebarRegion, typeof(SidebarView));
    }

    protected override void RegisterTypes(IContainerRegistry containerRegistry)
    {
        // Register Services
        containerRegistry.Register<IRestService, RestService>();

        // Views - Generic
        containerRegistry.Register<MainWindow>();

        // Views - Region Navigation
        containerRegistry.RegisterForNavigation<DashboardView, DashboardViewModel>();
