title: WPF - How to reference a UserControl compiled in another project in my WPF Windows application
body: <p>I created and compiled a WPF UserControl Library using VS 2008 .NET 3.5 on a Vista machine.
  Then I created a simple WPF Windows application. I added a reference to the compiled UserControl Library. Now when I try to add a  namespace in the XMAL code for the window I do not see my compiled UserControl namespace. What am I missing?</p>
