Prism.Avalonia

Prism.Avalonia provides your cross-platform Avalonia apps with Prism framework support so you can Navigate, create Dialog Windows and Notifications, provide Dependency Injection and internal Messaging easier than before! You will need both packages installed to get started.

Announcement!

• NEW: Official Prism.Avalonia Templates arrived!
• Prism.Avalonia v9.0.537 - Available!
• Check out the Upgrading to Prism v9.0 guide to avoid breaking changes in your apps

For more samples outside of this repo, check out:

• Avalonia Outlookish
• Learn PrismLibrary
• If you have samples, let us know and we'll feature them!

With Prism.Avalonia's logic and development approach being similar to that of Prism for WPF, so you can get started right away! Keep in mind, they are similar and not 1-to-1. Check out our Wiki and Avalonia Outlookish app for tips and tricks.

This project currently supports cross-platform Desktop applications (Windows, Linux, Mac). Support for Android, iOS, and web apps is still under evaluation; and is not 100%. Feel free to contribute and help us improve. 😃

Package Releases

Just like Prism.WPF or Prism.Maui, your project must reference both the Prism.Avalonia (Core) and Prism.DryIoc.Avalonia (IoC container) packages to work.

How to use

Program.cs

The default Avalonia entrypoint Program.cs does not need to be modified. Below is provided as a sample.

using System;
using Avalonia;

namespace SampleBaseApp;

internal sealed class Program
{
  // Initialization code. Don't use any Avalonia, third-party APIs or any
  // SynchronizationContext-reliant code before AppMain is called
  [STAThread]
  public static void Main(string[] args) => BuildAvaloniaApp()
    .StartWithClassicDesktopLifetime(args);

  // Avalonia configuration, don't remove; also used by visual designer.
  public static AppBuilder BuildAvaloniaApp()
    => AppBuilder.Configure<App>()
        .UsePlatformDetect()
        .WithInterFont()
        .LogToTrace();
}

App.axaml

<Application xmlns="https://github.com/avaloniaui"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             x:Class="SampleBaseApp.App"
             xmlns:local="using:SampleBaseApp"
             RequestedThemeVariant="Default">
  <!-- RequestedThemeVariant allows for the following types, "Default", "Dark", or "Light". -->

  <Application.Styles>
    <FluentTheme />
  </Application.Styles>
</Application>

App.axaml.cs

Notice:

We do not need the OnFrameworkInitializationCompleted() method. However, you must include base.Initialize(); in the Initialize() method to kick-start Prism.Avalonia.

Also, in your App.axaml you no longer need to device the <Design.DataContext>. Prism takes care of this for you! (:

using System;
using Avalonia;
using Avalonia.Markup.Xaml;
using Prism.DryIoc;
using Prism.Ioc;
using SampleBaseApp.Views;

namespace SampleBaseApp;

public partial class App : PrismApplication
{
  public override void Initialize()
  {
    AvaloniaXamlLoader.Load(this);
    base.Initialize();  // Required to initialize Prism.Avalonia - DO NOT REMOVE
  }

  protected override AvaloniaObject CreateShell()
  {
    Console.WriteLine("CreateShell()");

    return Container.Resolve<MainWindow>();
  }

  protected override void RegisterTypes(IContainerRegistry containerRegistry)
  {
    // Add Services and ViewModel registrations here

    Console.WriteLine("RegisterTypes()");

    // Services
    //// containerRegistry.RegisterSingleton<ISampleService, ISampleService>();

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

    // Dialogs
    //// containerRegistry.RegisterDialog<MessageBoxView, MessageBoxViewModel>();
    //// containerRegistry.RegisterDialogWindow<CustomDialogWindow>(nameof(CustomDialogWindow));
  }

    protected override void ConfigureModuleCatalog(IModuleCatalog moduleCatalog)
    {
      // Register modules
      //// moduleCatalog.AddModule<DummyModule.DummyModule1>();
    }
