I would like add one ResourceDictionary in my Window.Resources.
But I receive always the same message : the file 'infrastructure/dictionary.xaml' as not found.

I modified the property of ResourceDictionary file for select "ressource embeded".

My ResourceDictionary is in one folder :
C:\Users\JCo\Pictures\Screenpresso\2018-06-07_20h36_04.png

And i put this in my Windows.xaml :

    <Window.Resources>

        <ResourceDictionary Source="infrastructure/dictionary.xaml"/>

    </Window.Resources>
