Just need a little help with something...

So I'm trying to implement some new features that I found in the excellent update recently.

I'm trying to implement the adding of a new theme using the 'love' on as a test. Bellow is my complete code for the ResourceDictionary. I've tried it like this <ImageBrush Opacity=".1" ImageSource="/Assets/background.love.jpg" Stretch="UniformToFill" />

and like this <ImageBrush Opacity=".1" ImageSource="/CTaCInformationSystem;component/Assets/background.love.jpg" Stretch="UniformToFill" />

both give me this error: Provide value on 'System.Windows.Baml2006.TypeConverterMarkupExtension during the AppearanceManager.Current.ThemeSource = value.Source; method that is called on line 148 of the AppereanceViewModel.cs. The error put's it right at the Opacity='.1' in the code below.

The images is located in the Assets/background.love.jpg section in the source code.

Any ideas on how to fix this?

<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
                    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
                    xmlns:mui="http://firstfloorsoftware.com/ModernUI">

    <ResourceDictionary.MergedDictionaries>
        <ResourceDictionary Source="/FirstFloor.ModernUI;component/Assets/ModernUI.Dark.xaml" />
    </ResourceDictionary.MergedDictionaries>

    <Color x:Key="AccentColor">#e51400</Color>

    <!-- background image taken from http://good-wallpapers.com/ -->
    <Rectangle x:Key="WindowBackgroundContent" x:Shared="false">
        <Rectangle.Fill>
            <ImageBrush Opacity=".1" ImageSource="/CTaCInformationSystem;component/Assets/background.love.jpg" Stretch="UniformToFill" />
        </Rectangle.Fill>
    </Rectangle>

</ResourceDictionary>```

Found the issue. Needed to set the property of the image to Copy Always in the output directory for the Properties. Wow....that's what you get for self teaching c# 📦
