title: XmlParseException occuring in PresentationFramework for deploys only
body: <p>I am getting the following exception when I deploy my WPF app to another user's machine:</p>
  
  <blockquote>
    <p>An unhandled exception of type
    'System.Windows.Markup.XamlParseException'
    occurred in PresentationFramework.dll</p>
  </blockquote>
  
  <p>However, the WPF app runs fine when I open it.  The app crashes at StartUp with this message.  I've double-checked to make sure .NET 3.5 SP1 is installed on their machine, and also verified they can run a prototype WPF app.  Is there a good way to troubleshoot this type of error?</p>
  
  <p>Thanks!</p>
