ImageBrush throws exception when trying to set Window background

wpf image background imagebrush

I'm trying to set the background of my WPF window to an image but I'm getting this exception when I try to run it:

A first chance exception of type 'System.Windows.Markup.XamlParseException' occurred in PresentationFramework.dll Additional information: 'Provide value on 'System.Windows.Baml2006.TypeConverterMarkupExtension' threw an exception.' Line number '8' and line position '10'.

I don't want to add the image to the project, as I would like to be able to change the image at runtime. My intention is to use databinding to set the background picture during start-up once I have this bit working.

Source Code:

<Window x:Class="ColinsTest.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Title="Colin's Test Application" 
    WindowStyle="None"
    WindowState="Maximized">
<Window.Background>
    <ImageBrush 
        ImageSource="DeLaRue-Background.jpg"/>
</Window.Background>
<Grid></Grid>
</Window>

Any Ideas? Thanks

Wrong. It should be set to CONTENT not Resource.

Include in your project (use the file explorer)

Right click on the image > Properties > Advanced.

Build Action: Content

Copy to Output Directory: Copy always.
