title: Referenced library isn't copied
body: <p>I have <strong>ProjectA(WPFApplication)</strong> that references <strong>ProjectB(ClassLibrary)</strong>.
  Inside <strong>ProjectB</strong> i have wpf window that uses control from <strong>ThirdParty.dll</strong> wich i accordingly reference from <strong>ProjectB</strong>.</p>
  
  <p>The problem is that it doesn't find <strong>ThirdParty.dll</strong> in output folder of <strong>ProjectA</strong> and xaml parse runtime exceprion is raised.
  There is no <strong>ThirdParty.dll</strong> in GAC.
  Copy Locally is set to true.
  It works if i manually add in output folder of <strong>ProjectA</strong> that library and it also works if i use that <strong>ThirdParty.dll</strong> somwhere right in my cs files.</p>
  
  <p>How can i solve that?</p>
