title: WPF XBAP applications blank after second/third deploy?
body: <p>This has happened repeatedly on various machines in VS2008 and Visual C# 2008.</p>
  
  <p>I create an XBAP appliation.</p>
  
  <p>I click the green arrow and it works.</p>
  
  <p>I click Build/Publish and publish it to either a website or folder, it works.</p>
  
  <p>I make some changes, publish again, and I just get a white screen. Both browsers, can restart, always blank.</p>
  
  <p>It seems to be some kind of caching, etc. Has anyone had this happen to them and found a workaround?</p>
