title: Visual Studio 2010: suddently Locals, Immediate Window and Watches don't work
body: <p>I have this problem that a week ago, when debugging, suddently the "Locals" window is blank, the "Immediate Window" and Watches don't work and all return "Unable to evaluate the expression."</p>
  
  <p>Also the standard debugger display stopped giving me any info when I break the execution to check out stuff :-(</p>

  <p>I have played around with all the debugger settings, but none of them seems to have any effect what so ever on my problem.</p>
  
  <p>I did install the MVC3 RC1 and the Nupack just before my problem started, but removing them haven't solved anything. 
  I also removed all extensions and addons one by one to find the cause, but no result..</p>
  
  <p>Does anybody have an idea?</p>
  
  <p>I'm running on Win7 x64 on a Standard Core2 based laptop.</p>
