How to load a view with a converter in another assembly [MAUI.NET] - xaml

Question

I have a converter
using System.Globalization;
namespace WidgetsForRuntimeInjection.Converters
{
public class SampleBooleanConverter : IValueConverter
{
public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
{ ... }
public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
{ ... }
}
}
and a view
<?xml version="1.0" encoding="utf-8" ?>
<ResourceDictionary xmlns="http://schemas.microsoft.com/dotnet/2021/maui"
xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
xmlns:viewModels="clr-namespace:WidgetsForRuntimeInjection.ViewModels"
xmlns:converters="clr-namespace:WidgetsForRuntimeInjection.Converters;assembly=WidgetsForRuntimeInjection"
x:Class="WidgetsForRuntimeInjection.Views.SampleWidgetsForInjection">
<converters:SampleBooleanConverter x:Key="SampleBooleanConverter"/>
<DataTemplate x:DataType="viewModels:SwitchViewModel" x:Key="SwitchDataTemplate">
<Switch IsToggled="{Binding Value, Converter={StaticResource SampleBooleanConverter}}" IsEnabled="{Binding ReadWrite}"/>
</DataTemplate>
</ResourceDictionary>
both of them are in a single assembly that is build as dll.
Then in another assembly I am loading it and adding to an application resources.
var assembly = Assembly.LoadFile( ... path to dll... );
var resources = assembly.CreateInstance("WidgetsForRuntimeInjection.Views.SampleWidgetsForInjection");
App.Current.Resources.Add("SwitchDataTemplate", (resources as ResourceDictionary)["SwitchDataTemplate"]);
And I got error like that:
Microsoft.Maui.Controls.Xaml.XamlParseException: 'Position 7:6. Type converters:SampleBooleanConverter not found in xmlns clr-namespace:WidgetsForRuntimeInjection.Converters;assembly=WidgetsForRuntimeInjection'
But I can create an instance of this converter a line before (in this second assembly).
var converter = assembly.CreateInstance("WidgetsForRuntimeInjection.Converters.SampleBooleanConverter");
And of course with no converter scenario it all works like a charm.
How to make it work? I tried do Converter as DynamicResource and declaring namespace for converters differently.
UPDATE:
That is kind of weird, because it seems to work after I have added same in alternative way - in xaml.cs file like below:
public partial class SampleWidgetsForInjection : ResourceDictionary
{
public SampleWidgetsForInjection()
{
this.Add("SampleBooleanToColorConverter", new SampleBooleanToColorConverter());
InitializeComponent();
}
}

Answer 1

So it seems this is a workaround / solution:
public partial class SampleWidgetsForInjection : ResourceDictionary
{
public SampleWidgetsForInjection()
{
this.Add("SampleBooleanToColorConverter", new SampleBooleanToColorConverter());
InitializeComponent();
}
}
