title: SIlverlight XAP file not refreshing when debugging application
body: <p>I work on a team building Silverlight apps (version 4).  We use SVN and all work on separate parts of the code, and regularly update the project with latest code.  The Silverlight app runs from an ASP.NET web app.  We are having very frustrating issues when updating our code.  It seems like old versions of the XAP are being cached.</p>
  
  <p>Example:  Francisco changes the wording of a popup dialog, and commits his changes.  A very simple change, what could possibly go wrong?  I get the latest code.  I see the new code in my IDE (VS2010), and run it.  When I view that dialog, it does not have the new wording, even though I can see the new wording in my files.  I put a breakpoint on the code right where the change is, but when I run the app, the breakpoint is disabled!</p>
  
  <p>I try Clean build of the Silverlight and the Web host.  I kill my local ASP.NET development server.  I run the app - same thing!  I delete the xap from ClientBin.  No good.
  Each of us on the team are experiencing this issue.  Now we occasionally solve it, but are never sure what exactly fixed things, which is not satisfactory.</p>
  
  <p>There must be some setting or something that we are missing.  You would think that deleting the ClientBin xap file would solve it, as the new XAP must come from compiling the Silverlight app, right?</p>
  
  <p>If you've seen this problem before and have a real solution, please let me know.  (The solution of "format your hard drive and re-install everything" will NOT be accepted!)</p>
  
  <p>Thank you,</p>
