title: Moving MainWindow.xaml
body: <p>I've built a WPF app, which completely works now. However, to clean it up a bit I wish to move my <code>MainWindow.xaml</code> to the view folder I've created. After I've done this the application won't run and it gives me an <em>"Unknown build error"</em> which doesn't give any info on how to fix it...<br>
  What should I change in my <code>MainWindow.xaml</code> to let the app work properly again?  </p>
  
  <p>I've already changed</p>
  
  <pre><code>&lt;Window x:Class="projectname.MainWindow"&gt;
  </code></pre>
  
  <p>to</p>
  
  <pre><code>&lt;Window x:Class="projectname.view.MainWindow"&gt;
  </code></pre>
  
  <p>Should I change other stuff as well?</p>
