title: WPF C# XML resources in subfolder not getting built
body: <p>Currently in my project directory I have a folder called "Data" and in it I have two XML files that I use in my WPF application. I have set the XML files as "Resource" and the "Copy to Output Directory" option to "Copy Always". However, the following code throws a DirectoryNotFoundException because the files aren't being copied over to bin\debug when I build my application. </p>
  
  <p><code>return new Game(XDocument.Load("Data/Game.xml").Root);</code></p>
  
  <p>How do I make it so that everytime I build the files are moved over without having to do it manually everytime I change my XML?</p>
