Tested with MAUI Preview 14 and ArcGIS Runtime for .NET 100.13

Works on Windows and Android, but not IOS.

Code to create a MapView control for use in MAUI, and map it to the ArcGIS Runtime MapView.

using Microsoft.Maui.Handlers;
using EsriMap = Esri.ArcGISRuntime.Mapping.Map;

namespace MauiApp;

public interface IMapView : IView
{
    EsriMap Map { get; set; }
}

public class MapView : View, IMapView
{
    public static readonly BindableProperty MapProperty = BindableProperty.Create(
        nameof(Map), typeof(EsriMap), typeof(MapView));

    public EsriMap Map
    {
        get => (EsriMap)GetValue(MapProperty);
        set => SetValue(MapProperty, value);
    }
}

public class MapViewHandler : ViewHandler<IMapView, Esri.ArcGISRuntime.UI.Controls.MapView>
{
    public MapViewHandler() : base(PropertyMapper, CommandMapper)
    {
    }

    public static readonly PropertyMapper<IMapView, MapViewHandler> PropertyMapper = new PropertyMapper<IMapView, MapViewHandler>(ViewMapper)
    {
        [nameof(IMapView.Map)] = MapMap
    };

    public static readonly CommandMapper<IButton, IButtonHandler> CommandMapper = new CommandMapper<IButton, IButtonHandler>(ViewCommandMapper);

    private static void MapMap(MapViewHandler handler, IMapView view)
    {
        handler.PlatformView.Map = view.Map;
    }

    protected override Esri.ArcGISRuntime.UI.Controls.MapView CreatePlatformView()
    {
#if ANDROID
        return new Esri.ArcGISRuntime.UI.Controls.MapView(Context);
#else
        return new Esri.ArcGISRuntime.UI.Controls.MapView();
#endif
    }
}


Register with MAUI app builder in MauiProgram.cs

ConfigureMauiHandlers(handlers =>
{
    handlers.AddHandler(typeof(MapView), typeof(MapViewHandler));
});

 

Add ArcGIS Runtime NuGet packages.

<ItemGroup Condition="$(TargetFramework.Contains('-windows'))">
    <PackageReference Include="Esri.ArcGISRuntime.WinUI" Version="100.13.0" />
</ItemGroup>

<ItemGroup Condition="$(TargetFramework.Contains('-android'))">
    <PackageReference Include="Esri.ArcGISRuntime.Xamarin.Android" Version="100.13.0" />
</ItemGroup>

.NET 6-ios and .NET 6-android support isn't at this point supported, but considered preview. After we shipped Update 13, Microsoft updated their .NET 6 ios runtime with lots of breaking changes, which is what you're hitting.

We just shipped Update 13.1 a few days ago, and it's compiled with the latest, so (for now at least) that version should work with iOS (I've successfully used it). I have a MAUI sample here you can also play with and is quite similar to what you have: https://github.com/dotMorten/MauiPlayground/tree/main/Esri.ArcGISRuntime.Maui

Hi Morten,

Wondering if anything in the latest updates might impact iOS showing a MapView.  I'm at Visual Studio Version 17.3.0 Preview 3.0 and Runtime 100.14.1-preview3.  I get a map to show up in Windows but not in iOS 15.5 simulator.

Thanks -Joe

Thanks,
-Joe

There's a known issue with the ios simulator in 14.1. Please see the workaround I put here: https://community.esri.com/t5/arcgis-runtime-sdk-for-net-questions/ios-emulator-with-arcgisruntime-m...
