title: Find in Entire Solution in Visual Studio 2012 gets quite a lot of result from Temp folder
body: <p>In Visual Studio 2012, I tried to do some search in:
  <code>Find in Files-&gt;Entire Solution</code>, then I get quite a lot results from files in
  <code>C:\Uses\myusername\AppData\Local\Temp\</code>
  . The files take the name like <code>tmpE11.tmp.cs</code> or <code>tmpFBEE.tmp.cpp</code>, the contents are identical to some of the files in my solution.</p>
  
  <p>My guess is that it is caused or auto-generated by some crashes, but why are they reachable by the search? I doubt if I can simply delete them or not. </p>
