title: How to stop "Failed to delete the temporary file..." warnings from VS2012 compiler
body: <p>I have two rather large solutions that both experience the same problem.  The issue is that I am warned about an inability to delete temporary files.  The messages all look like this:</p>
  
  <blockquote>
    <p>Failed to delete the temporary file
    "C:\Users\Don\AppData\Local\Temp\tmp07197280428445c484ba0cda58178903.exec.cmd".
    The process cannot access the file
    'C:\Users\Don\AppData\Local\Temp\tmp07197280428445c484ba0cda58178903.exec.cmd'
    because it is being used by another process.</p>
  </blockquote>
  
  <p>I have seen suggestions of using pre-build commands to first delete things, but that is a lot of projects, and I'm not going there.</p>
  
  <p>Anyone know how else I might remedy this, that does not involve "fixing" each project individually?</p>
  
  <p>If it makes any difference, I'm compiling C# .NET 3.5 projects.</p>
