Prism.Avalonia

Prism.Avalonia provides your Avalonia apps with Prism framework support so you can navigate and perform dependency injection easier than before.

Prism.Avalonia's logic and development approach is similar to that of Prism for WPF so you can get started right away with Prism for Avalonia!

Install

Add the DryIoc package to your project:

Install-Package Prism.DryIoc.Avalonia -Version 8.1.97

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>();
        containerRegistry.RegisterForNavigation<SettingsView, SettingsViewModel>();
        containerRegistry.RegisterForNavigation<SidebarView, SidebarViewModel>();
    }
}
