title: WPF Equivalent of HTML base tag but for Source with relative path
body: <p>In my app, we can't use relative path for legacy reasons and we Sources like this <code>Source=&quot;/My.Project.Name;component/Resources/myImage.png&quot;</code>.</p>
  <p>So I've been wondering if there was a WPF equivalent of HTMl's <code>base</code> tag, allowing me to write <code>/My.Project.Name;component/</code> only once in my file and using relative path elsewhere.</p>
