How to set an image from Embedded resource using XAML in Xamarin.Forms

When setting an image source in code and pointing towards an embedded image in a specific folder in the PCL project ('Images' in this instance) I would do this:

backgroundImg.Source = ImageSource.FromResource("Myapp.Images." + imageName + ".jpg");

Is there a way to do this in XAML?

I managed to get this working by adding the ImageSource as an object in my View Model

public object ImageSource { get; set; }

Then populating the View Model as follows:

ImageSource = Xamarin.Forms.ImageSource.FromResource("ProjectName.Resources.Images.Image1.png", typeof(WalkthroughViewModel).GetTypeInfo().Assembly),

In the XAML, I simply referenced it as I would any other binding.

<Image Source="{Binding ImageSource}"/>

I am aware that the question doesn't necessarily use/require model-binding as you would with MVVM but I stumbled upon the answer provided above which helped me figure out the MVVM approach for anyone else who finds it useful. My particular use-case was for a CarouselView where I figured an embedded set of images would be useful.

@Code Pope is correct in his answer, but you also need to add an "ImageResourceExtension" as noted in the comments by @Gerald Versluis.

To do that just create a new file (class) "ImageResourceExtension.cs" like this:

using System;  
using System.Reflection;  
using Xamarin.Forms;  
using Xamarin.Forms.Xaml;

namespace ImageResourceExtension 
{
    [ContentProperty (nameof(Source))]
    class ImageResourceExtension : IMarkupExtension
    {
        public string Source { get; set; }

        public object ProvideValue(IServiceProvider serviceProvider)
        {
            if (Source == null) 
            {
                return null;
            }

            var imageSource = ImageSource.FromResource(Source, typeof(ImageResourceExtension).GetTypeInfo().Assembly);
            return imageSource;
        }
    } 
}

Then add xmlns:local="clr-namespace:ImageResourceExtension" to your xaml file like this:

<ContentPage xmlns="http://xamarin.com/schemas/2014/forms"
         xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
         xmlns:d="http://xamarin.com/schemas/2014/forms/design"
         xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
         xmlns:local="clr-namespace:ImageResourceExtension"
         ...

Now you can access an embedded resource using xaml code like this:

<Image Source="{local:ImageResource MyProject.Resources.Images.Logo.png}" />
