title: Visual Studio incredibly slow when renaming files
body: <p>I have a medium-sized solution with 99 projects that has recently started behaving weirdly: </p>
  
  <p>1) If I try to rename a file through the solution explorer, VS will seemingly hang, but after a long time (10+ minutes) it will complete the rename operation. </p>
  
  <p>2) I also noticed today that switching to between Debug and Release mode seems to freeze VS as well. So far I haven't let it run long enough to see if that actually completes.</p>
  
  <p>I've tried both Visual Studio 2012 and 2013, and both exhibit the same problem, so that seems to indicate the problem might not be with Visual Studio. I've tried to check in the event log if there's anything there, but nothing jumped out on me. I've also rebooted and run checkdisk, but it didn't find anything wrong.</p>
  
  <p>Running Windows 7 Professional on a fairly high-specced laptop with 8GB RAM and a new SSD</p>
  
  <p>Update: apparently if I have renamed a file once, I can keep renaming it (and other files in the solution) immediately. When I restart VS, it's slow again.  </p>
  
  <p>Update2: I left the computer running overnight to try to switch from Debug to Release, and it managed to do so in the 14ish hours between me leaving work and getting back here.</p>
