Where to add ObjectDataProvider in Application.Resources with ResourceDictionary

I followed this Tutorial and got stuck on the Create Instance of Config Settings Class-part. Here they just add the ObjectDataProvider in the Application.Resources. In my case there is already a ResourceDictionary in this context and I think this causes the problem.

My App.xaml:

<Application x:Class="MyApp.App"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             xmlns:config="clr-namespace:MyApp.ViewModels"
             StartupUri="MainWindow.xaml">

    <Application.Resources>
            <!-- create instance of config-settings class -->
            <ObjectDataProvider x:Key="AppSettingsDataProvider" ObjectType="{x:Type config:AppSettingsManager}"/>

            <ResourceDictionary x:Key="MainDictionary">
                <!-- also not working: -->
                <!--<ObjectDataProvider x:Key="AppSettingsDataProvider" ObjectType="{x:Type config:AppSettingsManager}"/>-->

                <ResourceDictionary.MergedDictionaries>
                    <ResourceDictionary Source="pack://application:,,,/Folder/file1.xaml" />
                    <ResourceDictionary Source="pack://application:,,,/Folder/file2.xaml" />
                    <!-- <ResourceDictionary Source="{Binding Source={StaticResource AppSettingsDataProvider}, Path=LoadMethod, Mode=OneWay}"/>-->
                </ResourceDictionary.MergedDictionaries>
            </ResourceDictionary>
    </Application.Resources>
</Application>

When I run the program my ResourceDictionary is not loaded anymore (Application.Current.Ressources.MergedDictionaries is empty), without the ObjectDataProvider everything works fine. Putting the ObjectDataProvider in the ResourceDictionary like suggested in the post Problems adding an ObjectDataProvider in resources did not help (is it different in the Application-class?). So where to put the ObjectDataProvider?
