Read values from XML files that aren't app.config or web.config

Windows 8/8.1 Store apps don't have app.configs or an equivalent. A common workaround is an embedded XML file that gets read using something similar to:

private static string LoadSetting(string settingKey)
{
    var assembly = typeof(AppConfig).GetTypeInfo().Assembly;

    using (var stream = assembly.GetManifestResourceStream("ABC.ConfigSettings.xml"))
    {
        var xmlDoc = XDocument.Load(stream);

        var appSettings = xmlDoc.Element("appSettings");

        var node = appSettings.Elements().Single(e => (string)e.Attribute("key") == settingKey);

        return (string)node.Attribute("value");
    }
}

It would be great if we could point ConfigInjector at an arbitrary embedded resource or string containing the properly formed XML.

Or even an arbitrary list of key value pairs, for other settings sources
