Caliburn.micro.maui

Caliburn Micro Maui beta now available

To use Caliburn.Micro with Maui use Visual Studio 2022 version 17.3 and install the maui workload. Then you can create a new Maui app. In the platforms folder delete the tizen folder. It is currently not supported by Caliburn.Micro.

Add a Caliburn.Micro.Maui nuget package to your solution. From the nuget package console you can use this command

Install-Package Caliburn.Micro.Maui -Version 4.0.247-g2be18de3b6 -Source https://www.myget.org/F/caliburn-micro-builds/api/v3/index.json

https://www.myget.org/feed/caliburn-micro-builds/package/nuget/Caliburn.Micro.maui#

In the platforms folder android modify the MainApplication class to this

[Application]
public class MainApplication : Caliburn.Micro.Maui.CaliburnApplication
{
   public MainApplication(IntPtr handle, JniHandleOwnership ownership)
    : base(handle, ownership)
  {
      Initialize();
  }

  protected override MauiApp CreateMauiApp() => MauiProgram.CreateMauiApp();

  protected override void Configure()
  {
      base.Configure();
  }

  protected override IEnumerable<Assembly> SelectAssemblies()
  {
      return new List<Assembly>() { typeof(App).Assembly };
  }
}

In the iOS folder modify AppDelgate to this

[Register("AppDelegate")]
 public class AppDelegate : Caliburn.Micro.Maui.CaliburnApplicationDelegate
{
    public AppDelegate()
    {
        Initialize();
    }

    protected override MauiApp CreateMauiApp() => MauiProgram.CreateMauiApp();
}

In the MacCatalyst folder modify AppDelegate to this

[Register("AppDelegate")]
public class AppDelegate : Caliburn.Micro.Maui.CaliburnApplicationDelegate
 {
    public AppDelegate()
   {
        Initialize();
   }

    protected override MauiApp CreateMauiApp() => MauiProgram.CreateMauiApp();
}

In the Windows folder modify the App.Xaml to this

<cal:CaliburnApplication
    x:Class="MauiApp2.WinUI.App"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:maui="using:Microsoft.Maui"
    xmlns:cal="using:Caliburn.Micro.Maui"
    xmlns:local="using:MauiApp2.WinUI">

</cal:CaliburnApplication>

Make sure you replace x:Class with your apps name

cs file

public partial class App : Caliburn.Micro.Maui.CaliburnApplication
{
    /// <summary>
    /// Initializes the singleton application object.  This is the first line of authored code
    /// executed, and as such is the logical equivalent of main() or WinMain().
    /// </summary>
    public App()
    {
	this.InitializeComponent();
	Initialize();
    }

     protected override MauiApp CreateMauiApp() => MauiProgram.CreateMauiApp();
 }

The App.Xaml in project root folder should be modified like this

<?xml version = "1.0" encoding = "UTF-8" ?>
<cal:MauiApplication xmlns="http://schemas.microsoft.com/dotnet/2021/maui"
         xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
         xmlns:local="clr-namespace:MauiApp2"
         xmlns:cal="using:Caliburn.Micro.Maui"
         x:Class="MauiApp2.App">
<Application.Resources>
    <ResourceDictionary>
        <ResourceDictionary.MergedDictionaries>
            <ResourceDictionary Source="Resources/Styles/Colors.xaml" />
            <ResourceDictionary Source="Resources/Styles/Styles.xaml" />
        </ResourceDictionary.MergedDictionaries>
    </ResourceDictionary>
</Application.Resources>
</cal:MauiApplication>

Replace xmlns:Local with your app name

The App.Xamal.cs file

public partial class App : Caliburn.Micro.Maui.MauiApplication
{
    public App()
    {
       InitializeComponent();

       Initialize();

      DisplayRootViewForAsync<MainViewModel>();
    }
 }
